The answer is C To eat producers and produce energy

C. To eat producers and produce energy.

Explanation:

In a food chain, a series of organisms are linked to together in a process whereby one eats the other and provides energy at each trophic level.

Every food chain typically starts with the producers who obtain the energy either through the sun or chemicals and make their own food,

The organisms who eat the producers are known as primary consumers and they are the ones who provide energy to the next trophic level of the secondary consumers .

The food chain is as follows:

Producer (plant) ---> primary consumer (herbivore)---> secondary consumer (carnivore)- --> tertiary consumer

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.
