Question 18
What will happen if deer is missing in the food chain given below?
Grass $\to$ Deer $\to$ Tiger

(a) The population of tiger increases
(b) The population of grass decreases
(c) Tiger will start eating grass
(d) The population of tiger decreases and the population of grass increases

Answer 1

Option (d) is correct.
If deer is missing in the given food chain, there will not be sufficient food for the tigers. Some of the tigers will die because of starvation and hence, the population of tigers will decrease. Now we know that grass is eaten by the deer, so, the population of grass will also increase because the deer is no more there to eat the grass.
