How does the survival of the fittest apply in an ecosystem that has more predators than prey? Wolves exert both direct and indirect effects on their ecosystem; influencing their prey, their prey influencing the plant and animal species beneath them, and so forth down the chain. The predators prey on herd animals like elk and deer that can overgraze an ecosystem if their populations are left unchecked. They build their nests inside trees that are often abandoned after the breeding season.
