Population Ecology

Front

What is immigration in population ecology?

Back

The movement into an area.

Front

What happens when a population grows past the ecosystem's carrying capacity?

Back

The population starts to die off to return to carrying capacity.

Front

Which letter represents exponential growth on a graph?

Back

B

Front

What type of growth does this graph show?

Back

Logistic growth.

Front

What are parasites, disease, and predators examples of?

Back

Density dependent limiting factors.

Front

What is carrying capacity?

Back

The maximum population size that an environment can sustain.

Front

What is the difference between density dependent and density independent factors?

Back

Density dependent factors are influenced by population size, while density independent factors affect populations regardless of size.

Front

What is exponential growth?

Back

A growth pattern where the population size increases rapidly over time, typically represented by a J-shaped curve.

Front

What is logistic growth?

Back

A growth pattern where the population grows rapidly at first, then slows as it approaches carrying capacity, typically represented by an S-shaped curve.

Front

What are limiting factors in population ecology?

Back

Environmental conditions that restrict the growth, abundance, or distribution of a population.
