NCERT Solutions Class 6 Science Chapter 2 - Diversity in the Living World

As you embark on Class 6 Science, you will quickly recognize that our planet is home to an incredible diversity of life. It's quite a journey to navigate this breadth of understanding, and it can feel a bit overwhelming! That's where the NCERT Solutions for Chapter 2: Diversity in the Living World come in. They are created to help you learn about this diversity in a more simplified, direct, and enjoyable manner.

Science is a process of exploration, observation, and understanding. This chapter is designed to create an understanding of how living things, whether they are organisms as small as microbes or as large as trees, can have specific features but also be similar. The focus here is appreciation of our commonalities and differences. This is an introduction to the science of diversity in life – not just the differences that will allow you to identify forms but also an appreciation of how we learn to be observant, inquisitive, and logical about our built and natural environments, which will serve you well beyond the classroom.

These NCERT Solutions for Class 6 Science Chapter 2 are meant to support students as they build an initial framework for understanding biodiversity and defining characteristics in living things. Using the NCERT Solutions will allow students to not only become familiar with important scientific concepts but also develop an appreciation for how life on Earth is interconnected.

2.0Key Concepts in Chapter 2: Diversity in the Living World

Chapter 2, "Diversity in the Living World," of the Class 6 Science NCERT textbook, introduces students to the basic ideas of different kinds of living organisms, the habitats of those living organisms, and the basic classifications of those living organisms.

Introduction to Diversity: The chapter begins with the big idea of the extremely diverse living things we see around us – from plants and animals to smaller organisms – there is a concept about biodiversity.

Characteristics of Living Things: In addition, it shows students what can be defined as "living" based on general characteristics; for example:

• Movement: How living things move.
• Growth: How they grow over time.
• Respiration: How they breathe.
• Reproduction: How they produce more of their kind.
• Response to Stimuli: How they react to changes in their environment.
• Excretion: How they remove waste from their bodies.
• Nutrition: How they obtain food.

Habitat and Adaptation: The chapter presented the notion that living organisms reside in distinct locations (their habitat) and have distinct features (adaptations) that assist them in surviving those habitats. Examples are frequently included: 

• Terrestrial habitats: Forests, grasslands, deserts, mountains. 
• Aquatic habitats: ponds, lakes, rivers, oceans.

Classification of Living Things: It offers a basic understanding of how living things are classified, typically into:

• Plants: Including some examples of plant types (trees, shrubs, herbs, climbers, creepers).
• Animals: Including some example examples of animal classifications (mammals, birds, fish, insects, amphibians, reptiles).

Note also that there is some implied reference to microscopic organisms (but not too much detail at this stage).

• Interdependence: The chapter provides an indirect introduction to the concept that living things rely on one another and their surrounding environment to survive.
• Examples from real life: The chapter has examples from every day to help the science ear concepts to life. For example, students can look closely at the variety of animals and plants found in their local vicinity.

Here are some common subtopics covered in this chapter:

• What is Diversity in Living Things?
• • Definition of diversity.
  • Examples of different living organisms.
• Characteristics of Living Organisms
• • Need for food (Nutrition)
  • Growth
  • Respiration
  • Response to stimuli
  • Movement
  • Excretion
  • Reproduction
• Habitats
• • Terrestrial habitats (Forest, grassland, desert, mountain)
  • Aquatic habitats (Pond, lake, river, ocean)
  • Adaptations of organisms to their habitat
• Plants: A Closer Look
• • Parts of a plant (root, stem, leaf, flower, fruit)
  • Types of plants (herbs, shrubs, trees, climbers, creepers)
• Animals: A Closer Look
• • Different types of animals (mammals, birds, fish, insects, reptiles, amphibians)
  • How animals move, eat, and reproduce
• Interdependence in Nature
• • Food chains (basic concept)
  • How plants and animals depend on each other

• Here are two types of seeds. What differences do you find among the roots and leaf venation of their plants?
  
  (a) Wheat
  
  (b) Kidney bean Ans. Wheat is a monocot and all monocots have parallel venation and fibrous root system. Kidney beans are dicots and all dicots have reticulate venation and tap root system.
• Names of some animals are given below. Group them based on their habitats. Write the names of aquatic animals in the area marked 'A' and terrestrial animals in the area marked 'B'. Enter the names of animals living in both habitats in part ' $C$ '. Horse, Dolphin, Frog, Sheep, Crocodile, Squirrel, Whale, Earthworm, Pigeon, Tortoise.
  
  Ans. A represents aquatic organisms E.g.- Dolphin, whale B represents terrestrial organisms E.g.- horse, squirrel, earthworm, pigeon, tortoise, crocodile. C represents Amphibians E.g.- frog
  
  (a) Mountain goat
  
  (b) Goat found in plains
• Manu's mother maintains a kitchen garden. One day, she was digging out radish from the soil. She told Manu that radish is a kind of root. Examine a radish and write what type of root it is. What type of venation would you observe in the leaves of radish plant? Ans. Radish has tap root system and reticulate venation.
• Look at the image of a mountain goat and a goat found in the plains. Point out the similarities and differences between them. What are the reasons for these differences? Ans.

Differences -

• Group the following animals into two groups based on any feature other than those discussed in the chapter cow, cockroach, pigeon, bat, tortoise, whale, fish, grasshopper, lizard. Ans. These animals can be categorized into two category terrestrial and aquatic Terrestrial organisms include cow, pigeon, bat, cockroach, grasshopper, lizard, tortoise, and aquatic organisms include whale, fish.
• As the population grows and people want more comfortable lives, forests are being cut down to meet various needs. How can this affect our surroundings? How do you think we can address this challenge? Ans. Effect of deforestation - (A) Loss of biodiversity (B) Changes in climate (C) Soil erosion We can address this challenge by establishing more protected areas. We should plant more trees near our surrounding.
• Analyse the flowchart. What can be examples of 'A' and 'B'?
  
  Ans. The plants that have reticulate venation in their leaves can be mango, rose, mustard etc. and the plants that do not have reticulate venation (i.e. they have parallel venation) can be wheat, rice, maize etc.
• Raj argues with his friend Sanjay that "Gudhal (hibiscus) plant is a shrub". What questions can Sanjay ask for clarification? Ans. He can ask some questions for clarification like - (i) What is the nature of its stem? (ii) What is the height of the hibiscus?
• Based on the information in the table, find out examples of these plants for each group.

(a) What other similarity do plants of group A have? (b) What other similarity do plants of group B have? Ans. Example of group A and B is Pea and rice respectively. (a) Plants of group A have leaves with reticulate venations. (b) Plants of group B have leaves with parallel venations.
