Answer:

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

Therefore, whenever the bird will hear the ringing sound it will search for key to be picked.
