Answer:
Competition
Step-by-step explanation:
In biology, density-dependent limiting factors directly affect the growth of a population, which normally cause a decrease in the number of individuals in an ecosystem.
There are different density-dependent limiting factors, and one of them is competition. Animals, either from the same species or different species, are always competing for resources, such as food (prey). This factor intensifies along with the increase of the population, that is, the more individuals are in a given area, the availability of prey will decrease and the competition will increase.
