Front

What is a density-independent factor?

Back

An environmental factor that affects a population regardless of its density, such as natural disasters.

Front

What happens to a population when the number of births equals the number of deaths?

Back

The population size remains stable.

Front

What is carrying capacity?

Back

The maximum number of individuals of a species that an environment can sustainably support.

Front

What is mutualism?

Back

A type of symbiosis where both species benefit from the interaction.

Front

What is commensalism?

A type of symbiosis where one species benefits and the other is neither helped nor harmed.

Front

What is parasitism?

Back

A type of symbiosis where one species benefits at the expense of the other.
