C. Population sizes are limited by the amount of resources that are available.

Explanation:

Population regulation is a phenomenon in which the population of a species utilizing the same resources meets the limiting factors. These limiting factors limit their growth and size.

The limiting factors can be density-dependent or density-independent limiting factors. The density-dependent limiting factors cause reduction in per capita growth of a population when the size of the population living in an area grows larger than the source of food available in that area.
