A species that generally has a wide range of things in their diets as well as a relatively large area of habitat.

Front

Define carrying capacity in population ecology.

Back

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

Front

What is logistic growth?

Back

Population growth that starts exponentially but slows as the population reaches carrying capacity.

Front

What is a density-dependent factor?

Back

A factor that affects population size in relation to the population's density, such as food availability.

Front

What is a density-independent factor?

Back

A factor that affects population size regardless of the population's density, such as natural disasters.

Front

What is the difference between r-selected and K-selected species?

Back

r-selected species produce many offspring with low parental care, while K-selected species produce fewer offspring with high parental care.
