Back

Factors that limit a population size but depend on the size of the population to have an impact.

What are Density Independent Factors?

Back

Front

What is carrying capacity?

Back

The maximum number of individuals of one species that the environment can support.

Front

What happens to population growth as resources become less available?

Back

Any factor that restricts the size of a population.

Front

What is exponential growth?

Back

A rapid increase in population size when resources are abundant.

Front

Back

Population growth that levels off as it approaches carrying capacity.
