1. How does food help us? 

Answer.  Food provides the energy needed for daily activities, supports growth and development, repairs damaged tissues, and keeps the immune system strong. It also supplies essential nutrients like vitamins, minerals, proteins, and carbohydrates that are vital for maintaining good health. 

2. How do green plants make their own food? 

Answer. Green plants make their own food through a process called photosynthesis. They use sunlight, carbon dioxide from the air, and water from the soil to produce glucose (food) and oxygen. Chlorophyll, the green pigment in leaves, helps capture sunlight for this process. 

3. Name two plants for each of the following parts we eat: 

   (a) Roots: Carrot, Radish 

   b) Stems: Potato, Sugarcane 

    (c) Leaves: Spinach, Lettuce 

   (d) Flowers: Cauliflower, Broccoli 

   (e) Fruits: Apple, Banana 

   (f) Seeds: Peas, Beans 

4. Write the names of any five animal products that we eat as food. 

   – Eggs 

   – Chicken 

   – Fish 

   – Honey 

   – Milk 

5. Why is milk considered a nutritious food? Name three animals that give us milk. 

Answer. Milk is rich in calcium, protein, vitamins (like D and B12), and minerals, which help in bone development, muscle growth, and overall health. 

 Three milk-giving animals: Cow, Goat, Buffalo 

6. What are milk products? List any five milk products that we eat. 

 Answer. Milk products are foods made from milk through processing. Examples: 

   – Cheese 

   – Yogurt (Curd) 

   – Butter 

   – Ghee 

   – Ice Cream 

7. Describe how animals can be grouped according to the food they eat, with examples. 

 Answer. Animals can be classified into three groups based on their diet: 

   – Herbivores: Eat only plants (e.g., Cow, Deer, Rabbit). 

   – Carnivores: Eat other animals (e.g., Lion, Tiger, Eagle). 

   – Omnivores: Eat both plants and animals (e.g., Bear, Crow, Human). 

8. What are herbivorous animals? Give three examples and their special feeding features. 

Answer. Herbivores are animals that feed only on plants. Examples: 

   – Cow: Flat teeth for grinding grass. 

   – Deer: Sharp incisors to bite leaves. 

   – Rabbit: Strong front teeth to chew vegetables. 

9. What are carnivorous animals? Give three examples and their special feeding features. 

Answer. Carnivores are animals that hunt and eat other animals. Examples: 

 Lion: Sharp claws and strong jaws for tearing flesh. 

 Eagle: Hooked beak to rip meat. 

 Snake: Venom or constriction to capture prey. 

10. What are omnivores? Give two examples.

Answer. Omnivores are animals that eat both plants and other animals. They have a flexible diet, which helps them survive in different environments.
Examples:

• Humans (eat vegetables, fruits, meat, and dairy)
• Bear (consumes berries, fish, and small mammals)
• What are scavengers? Give two examples.
  
  

Answer.  Scavengers are animals that feed on dead or decaying organisms instead of hunting live prey. They help keep the environment clean by consuming waste.
Examples:

• Vulture (feeds on dead animals)
• Hyena (scavenges leftover kills from other predators)
• What are decomposers? Give two examples.

Answer. Decomposers are organisms (usually bacteria or fungi) that break down dead plants and animals into simpler substances, returning nutrients to the soil.
Examples:

     Earthworms break down organic matter in soil)

    Mushrooms (Fungi) decompose dead wood and leaves.
