Population growth is limited by density-dependent factor such as

predation, water supply, parasitism, migration, diseases, waste accumulation, food availability, and competition.

Explanation:

A population can be defined as the total number of living organisms living together in a particular place and sharing certain characteristics in common.

Population regulation can be defined as a biological process that balances limiting factors affecting the growth of a population based on density.

Basically, the factors that regulate the growth of a population are divided into two (2) main categories and these includes;

I. Density-independent factors.

II. Density-dependent factors.

Density-dependent are regulating factors such as predation, diseases, and competition that affect the size of the population of living organisms through decreasing or increasing mortality and birth rate.

This ultimately implies that, population growth is limited by density-dependent factors such as predation, parasitism, migration, diseases, waste accumulation, food availability, water supply, and competition within the population.
