Answer:

the maximum population size that a particular environment can support.

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.

Generally, these populations may be divided into a fraction of the population (subpopulation) based on certain factors and reasons.

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

Furthermore, density-independent factors do not have an increasingly greater effect as a population's density increases. Thus, its effect are reduced as a population's density increases in size.

Carrying capacity is the maximum population size that a particular environment can support. The carrying capacity of an environment is denoted by the letter k.
