(b) Grass, goat and human

(c) Goat, cow and elephant

(d) Grass, fish and goat

 

Answer

Let’s study all the examples

 

(a) Grass, wheat and mango

Grass, wheat and mango are all producers.

Hence, they can not form a food-chain.

 

(b) Grass, goat and human

Grass is a producer.

Goat is a herbivore which eats grass.

Human is an omnivore which can eat goat.

Hence, (b) forms a food chain.

 

(c) Goat, cow and elephant

Goat, cow and elephant are all herbivores.

Hence, they can’t feed on one another.



(d) Grass, fish and goat

Grass is a producer.

Fish is an omnivore.

But, goat is a herbivore. Therefore, it can feed on the fish. 

Hence, they cant form a food chain.
