What is the most likely effect on the energy pyramid if all producers are removed from the ecosystem?
a) the energy pyramid will not change.
b) the energy pyramid will become inverted.
c) the energy pyramid will be completely disturbed.
d) the energy pyramid will begin with primary consumers.

Option C, The energy pyramid will be completely disturbed.

Explanation:

Producers include organism that are able to produce food and energy for themselves and all other species.

Since they have the capability of feeding and acting as source of energy for others , all food chains start from producers only.

In case all producers are removed from ecosystem, then none of the organism in any trophic level will be able to survive and the entire food chain and ecosystem will come to a halt state.

Thus, option C is correct.
