c. more producers than consumers
d. fewer primary consumers than tertiary consumers
select the best answer from the choices provided

C

Explanation:

This is because energy transfer up the food chain or food web is very inefficient. There needs to be more even producers to sustain more consumers. This is because, for every biomass of producers that primary consumers consume, only 10% is captured and converted into biomass. The rest is lost in inefficiencies especially in the form of heat. This goes up the chain such that, the number of secondary consumers will always be lower than that of primary consumers and the number of tertiary consumers will always be fewer than secondary consumers in a sustainable ecosystem. This is why the energy pyramid tapers to the top.
