Question

What will happen to an ecosystem if

a. All producers are removed;

b. All organisms of herbivore level are eliminated; and

c. All top carnivore population is removed.

Ans.

a. Reduction in primary productivity. No biomass available for consumption by higher

trophic levels/heterotrophs and hence heterotrophs also die of starvation.

b. Increase in primary productivity and biomass of producers. Carnivore population will

subsequently dwindle due to food shortage.

c. Increase in number of herbivores which leads to over-grazing by herbivores, finally

resulting in desertification.​
