Environmental Balance — EVS STD 5 — Question

In nature, Plants are food for one small animal. This smaller animal is the food for a larger animal which in turn is a food for another larger animal. Thus we see that one living thing is connected to another living thing for their food, and each component or living thing is the food for the next one. Therefore we can say the components form a chain. Such a biological chain is called a food chain. Example of a food chain.

Plants → Grasshopper → Frog → Snake → Kite

The plant is eaten by the grasshopper which is eaten by the frog. The frog is eaten by the snake which is eaten by the kite.
