Ecology: Populations

Front

What is a Density Independent limiting factor?

Back

A limiting factor that affects any size population regardless of its density, such as natural disasters like tornadoes.

Front

What is a Density Dependent limiting factor?

Back

A limiting factor that affects larger populations and is usually biotic, such as predators or disease.

Front

How can a population's size be increased?

Back

By having members immigrate into the population.

Front

What is Logistic Growth?

Back

A growth pattern where a population grows rapidly at first and then slows or stops as it reaches carrying capacity.

Front

What is Emigration?

Back

The movement of individuals out of a population or area.

Front

What is Immigration?

Back

The movement of individuals into a population or area.

Front

What is Carrying Capacity?

Back

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

Front

What is Exponential Growth?

Back

A growth pattern where a population increases rapidly without any limiting factors.

Front

What is a J Curve in population growth?

Back

A graphical representation of exponential growth, where the population size increases dramatically.

Front

What is a Biotic Factor?

Back

A living component of an ecosystem that affects the population, such as competition, predation, and disease.
