Population Growth

Front

What is exponential growth?

Back

A type of growth that occurs under ideal conditions, where the population size increases rapidly over time.

Front

What is logistic growth?

Back

A type of growth that occurs when a population's growth slows as it approaches the carrying capacity of its environment.

Define emigration.

Back

The act of leaving one's resident population to settle in another.

Front

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

Back

Density-dependent factors are influenced by population density (e.g., competition, disease), while density-independent factors affect populations regardless of their density (e.g., natural disasters).

Front

What is a population?

Back

Front

What is the significance of the logistic growth curve?

Back

It illustrates how populations grow rapidly at first, then slow down as they approach carrying capacity.

Front

What is a biotic factor?

Back

A living component of an ecosystem that affects the population (e.g., predators, food sources).
