Question

What will happen if deer becomes extinct in the food chain given below?
Grass $\to$ Deer $\to$ Tiger

• A. The population of tiger increases.
• B. The population of grass decreases.
• C. The tiger will start eating grass.
• D. The population of tiger decreases and the population of grass increases.

Answer 1

The correct option is D

The population of tiger decreases and the population of grass increases.

In this food chain, if deer would be missing, the population of tiger will decrease as they will not get food (deer) and the population of producers or grass will increase as it will not be eaten up by deer. This means that the population of any species in the food chain will affect the population of all the other species.
