1. An example of a biotic factor is spiders and insects. Spriders prey on the insects, but the insects are able to reproduce constantly and remain in even birth and death rate. Another example of a biotic factor is sucker fish and sharks. The sucker fish clean the sharks and in return the sharks don't kill the fish. Another example is a bobcat and rabbits, the bobcats eat the rabbits and rabbits reproduce fast holding onto an even death and birth rate.
