Answers
A :
From animals, we get eggs, milk, butter, cheese, meat, fish, and chicken. Green plants are the main source of food for both humans and animals. ... There are different parts of plants which serves us with different types of food. Food obtained from roots – beetroot, carrot, radish, turnip, and sweet potato.
B:
Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.
C:
Animals are called consumers. This is because they cannot make their own food, so they need to consume (eat) plants and/or animals.
Types of animals based on food habits. Mostly the animals are either herbivorous or carnivorous or omnivorous. The herbivorous animals take only plants and/or plant products of their food. The carnivorous animals, such as, tiger, lion, crocodile, etc. live on only flesh.
