Quick Chapter Recap: Diversity in the Living World

Before attempting the worksheet, revisit these core concepts from CBSE Class 6 Science Chapter 2. Living organisms exhibit seven key characteristics: movement, respiration, nutrition, excretion, growth, reproduction and sensitivity to stimuli. Non-living things lack these life processes. A habitat is the natural environment where an organism lives, providing food, water, shelter and suitable conditions for survival. NCERT Class 6 Science identifies four major habitat types: terrestrial (land-based like deserts and forests), aquatic (water-based including oceans, rivers and ponds), arboreal (tree-dwelling) and aerial (organisms that fly or spend significant time in air). Adaptations are special features that help organisms survive in their specific habitats — for example, cacti have thick stems to store water in deserts, while fish possess gills for underwater breathing. Classification groups similar organisms together based on shared characteristics, making it easier to study the vast diversity of life on Earth. The chapter emphasizes observation skills, asking students to identify patterns in how different plants and animals are suited to their environments.

Living organisms: movement, respiration, nutrition, excretion, growth, reproduction, sensitivity
Habitats: terrestrial, aquatic, arboreal, aerial with specific examples from Indian ecosystems
Adaptations: structural and behavioural changes for survival in specific environments
Classification: grouping organisms by shared characteristics to understand diversity

Section A: Multiple Choice Questions (1 mark each)

This section contains six carefully crafted multiple-choice questions that test your understanding of fundamental concepts from CBSE Class 6 Science Chapter 2. Each question has four options with only one correct answer. These MCQs cover the distinguishing features of living and non-living things, different types of habitats as described in NCERT Class 6 Science, and basic adaptations seen in common plants and animals. When answering, read each question twice, eliminate obviously incorrect options first, and then choose the most accurate answer based on chapter definitions. MCQs are a favourite question type in CBSE examinations because they test recall, comprehension and application simultaneously. Pay special attention to keywords like 'all of the following except', 'most appropriate' and 'primarily' which often hold the key to the correct answer. For Class 6 Science notes revision, these questions mirror the pattern used in school periodic tests and the annual examination. Time management tip: allocate approximately one minute per MCQ, marking difficult questions for review if time permits at the end.

Q1. Which of the following is NOT a characteristic of living organisms? (a) Growth (b) Respiration (c) Rusting (d) Reproduction
Q2. An aquatic habitat is characterized by: (a) Scarcity of water (b) Presence of water bodies (c) Extreme temperatures (d) Sandy soil
Q3. Which adaptation helps a cactus survive in desert conditions? (a) Broad leaves (b) Thick stem for water storage (c) Shallow roots (d) Bright flowers
Q4. Fish breathe through: (a) Lungs (b) Skin (c) Gills (d) Nose
Q5. Arboreal animals primarily live: (a) In water (b) Underground (c) On trees (d) In deserts
Q6. Which of these is a non-living thing? (a) Bacteria (b) Virus (c) Stone (d) Seed

Section B: Fill in the Blanks (1 mark each)

Section B presents five fill-in-the-blank questions designed to test your recall of specific terms and concepts from the Diversity in the Living World chapter. These questions require you to remember exact terminology used in NCERT Class 6 Science textbooks, making them excellent for revision and reinforcement of key vocabulary. When approaching fill-in-the-blank questions, read the entire sentence first to understand the context, then identify what type of word is needed — a habitat name, an adaptation feature, a life process, or a classification term. The blank usually represents a critical concept that completes the scientific statement logically. In CBSE Class 6 Science examinations, spelling accuracy matters, so practice writing scientific terms correctly. These questions often appear in 10-mark question papers during periodic assessments. If you are unsure, think about what you learned in each section of the chapter and try to match the sentence context with chapter headings. Class 6 Science solutions and notes emphasize these precise terms because they form the foundation for higher classes. After completing this section, cross-check your answers with the answer key provided at the end of this worksheet to identify any gaps in terminology retention.

Q7. The natural surroundings where an organism lives is called its __________.
Q8. __________ is the process by which living organisms produce young ones of their own kind.
Q9. Animals living in water are said to have an __________ habitat.
Q10. The ability of organisms to sense changes in their environment is called __________.
Q11. Desert plants like cactus have __________ instead of broad leaves to reduce water loss.

Section C: True or False (1 mark each)

This section contains six statements related to CBSE Class 6 Science Chapter 2 on Diversity in the Living World. Your task is to determine whether each statement is True or False based on concepts taught in the NCERT curriculum. True/False questions test your ability to recognize accurate scientific facts and distinguish them from common misconceptions. Read each statement carefully and look for absolute words like 'all', 'never', 'always' and 'only' — these often indicate a false statement because science usually has exceptions. However, do not assume every statement with absolute language is automatically false; evaluate it against what you have learned in the chapter. These questions cover living characteristics, habitat types, adaptations and basic classification principles. In CBSE examinations, True/False questions sometimes include a follow-up requirement to correct false statements or justify your answer, so be prepared to explain your reasoning. For effective practice, first answer all questions, then review each statement by recalling the specific page or section from your Class 6 Science notes where the concept was explained. This section helps reinforce accurate scientific understanding and eliminates common errors that students make during exams.

Q12. All living organisms need food, air and water to survive. (True/False)
Q13. Terrestrial habitats are found in water bodies like rivers and oceans. (True/False)
Q14. Camels store water in their humps. (True/False)
Q15. Respiration is the process of taking in food. (True/False)
Q16. Aerial animals spend most of their time flying or in the air. (True/False)
Q17. Non-living things can grow by adding similar material to their bodies. (True/False)

Section D: Short Answer Questions (2-3 marks each)

Section D comprises five short-answer questions, each requiring 2-3 well-structured sentences or 30-50 words. These questions demand more than simple recall; you must explain concepts, provide examples and demonstrate understanding of relationships between ideas presented in CBSE Class 6 Science Chapter 2. When writing short answers, begin with a direct response to the question, then elaborate with one or two supporting points or examples from the chapter. Use proper scientific terminology from NCERT Class 6 Science — for instance, say 'terrestrial habitat' rather than just 'land', or 'adaptation' instead of 'special feature'. Structure is important: if the question asks for differences, present them in a comparative format; if it asks for examples, provide at least two with brief descriptions. In CBSE marking schemes, examiners award marks for accurate content, relevant examples and clear expression. Avoid writing long paragraphs for 2-mark questions; concise, focused answers score better. These questions typically appear in the 40-mark theory paper and are considered scoring questions if you have revised Class 6 Science solutions thoroughly. Practice writing answers within the word limit to develop the skill of conveying maximum information in minimum words, a crucial examination strategy.

Q18. List any four characteristics that distinguish living organisms from non-living things. (2 marks)
Q19. What is a habitat? Give two examples of aquatic habitats found in India. (2 marks)
Q20. Explain how the thick fur of polar bears is an adaptation to their environment. (2 marks)
Q21. Why do desert plants have long roots? Mention one other adaptation of desert plants. (3 marks)
Q22. Differentiate between terrestrial and arboreal habitats with one example each. (3 marks)

Section E: Long Answer and HOTS Questions (5 marks each)

Section E contains three long-answer questions worth 5 marks each, designed to test higher-order thinking skills (HOTS) and comprehensive understanding of CBSE Class 6 Science Chapter 2. These questions require detailed explanations spanning 80-120 words, often asking you to describe processes, compare multiple concepts, or apply learning to new situations. A well-structured 5-mark answer typically includes: an introduction defining the main concept, 3-4 distinct points with explanations, relevant examples from NCERT Class 6 Science or real life, and a brief concluding statement if appropriate. Use paragraph breaks or bullet points for clarity. HOTS questions go beyond textbook reproduction — they may ask 'why' and 'how' rather than just 'what', requiring you to analyze relationships and demonstrate deeper understanding. For instance, instead of just listing adaptations, you might need to explain why specific adaptations evolved in response to environmental challenges. In CBSE examinations, 5-mark questions carry significant weight and proper time management is essential; allocate 7-8 minutes per question. Refer to Class 6 Science notes to gather comprehensive information, but express answers in your own words to show genuine understanding rather than rote memorization. These questions prepare you for the analytical thinking required in higher classes.

Q23. Describe the main characteristics of living organisms. Explain each characteristic briefly with an example. (5 marks)
Q24. What are adaptations? Explain with three examples how different animals are adapted to their aquatic habitats. (5 marks)
Q25. Classification helps us study the diversity of living organisms. Explain this statement with suitable examples of how organisms can be grouped. (5 marks)

Section F: Case Study Question (4 marks)

The case study question integrates multiple concepts from CBSE Class 6 Science Chapter 2 into a real-world scenario, testing your ability to apply theoretical knowledge to practical situations. Read the passage carefully — often twice — before attempting the questions, underlining key information as you go. Case studies typically present a situation involving habitats, adaptations or organism diversity, followed by 3-4 short questions worth 1-2 marks each. The total marks for this section add up to 4. This question type has gained prominence in recent CBSE examination patterns because it assesses comprehension, application and analytical skills simultaneously. When answering, refer back to specific details in the passage rather than relying solely on general chapter knowledge; examiners look for evidence that you have understood the given scenario. However, you should also connect the case study to concepts from NCERT Class 6 Science to demonstrate comprehensive understanding. For example, if the passage describes a pond ecosystem, link it to the aquatic habitat characteristics you studied. Case study questions are excellent preparation for competitive examinations and higher-class biology where application-based learning becomes increasingly important. Practice these regularly using Class 6 Science solutions to become comfortable with the format.

Tips for Effective Worksheet Practice

To maximize learning from this CBSE Class 6 Science Chapter 2 worksheet, follow these evidence-based strategies used by toppers. First, simulate exam conditions: print the worksheet, set a timer for 60 minutes, and attempt it without referring to notes or textbooks. This builds time management skills and identifies your true preparation level. Second, after completing the worksheet, take a 10-minute break before checking answers — this prevents the discouragement that sometimes comes from immediate correction and allows your brain to consolidate what you have recalled. Third, when reviewing the answer key, do not just mark correct or incorrect; for every mistake, write a one-line note explaining why you erred, whether it was a concept gap, careless reading, or exam pressure. These error logs become goldmines for revision before the actual CBSE examination. Fourth, redo only the incorrect questions after a gap of two days to check if the concept has now solidified. Fifth, discuss interesting questions from the worksheet with family members or classmates — teaching concepts to others is one of the most effective learning methods. Finally, maintain a separate notebook for Class 6 Science notes specifically for Chapter 2, where you compile worksheet learnings, difficult terms, and quick revision points. Regular worksheet practice with active learning strategies outperforms passive reading of NCERT Class 6 Science textbooks.

Attempt the worksheet in timed conditions without referring to Class 6 Science solutions initially
Create an error log noting why each mistake occurred, transforming failures into learning opportunities
Redo incorrect questions after 2-3 days to verify that conceptual gaps have been addressed
Discuss challenging questions with peers or family to deepen understanding through teaching
Compile a quick-revision sheet from worksheet concepts for final exam preparation
