(B) Deer, cheetah, eagle, butterfly
(C) Elephant, cow, rabbit, goat
(D) Rabbit, vulture, tiger, deer

Answer 1

Hint: The organisms that produce their own food are called autotrophs. The green plants come under this category and are called producers. The other organisms depend on them for their food. They are called heterotrophs. This heterotrophs classified into different types based on its prey.

Complete Answer:
- The heterotrophs are again divided into three types as the herbivores, carnivores and the omnivores. If the organism feeds only on the plants, they are called herbivores. The rabbit, cattle, deer comes under this category.
- If the organisms feed on the herbivores they are called primary carnivores and if the organism feeds on the other carnivores they are called secondary carnivores. The lion, tiger etc. are the examples of the carnivores.
- The organisms that feed on the dead and decaying matter are called omnivores. The vulture comes under this category. In the given option the elephant, cow, ribbit and the goat are all herbivores. Except this option, others may consist of the carnivores and the omnivores.

Thus the option (C) is correct.

Note: The organisms that come under these categories forms the food chain. The food chain is the chain in which the organisms of producers, herbivores, and carnivores are interlinked to each other. This food chain helps in the survival of all the organism and helps in the maintenance of the existence of biodiversity.
