Populations

Front

What is a limiting factor?

Back

A biotic or abiotic resource in the environment that causes population size to decrease.

Front

What is logistic growth?

Back

A typical population growth pattern where growth slows as the population reaches carrying capacity.

Front

What happens if a population exceeds its carrying capacity?

Back

The birthrate must fall.

Front

What is a density-dependent factor?

Back

A factor that affects population size based on the population density, such as competition, predation, and parasitism.

Front

What is an example of a density-independent factor?

Back

Natural disasters, which affect populations regardless of their density.

Front

What is carrying capacity?

Back

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

Front

What is the difference between a predator and prey?

Back

A predator hunts and eats other organisms (prey) for food.

Front

What is exponential growth?

Back

A growth pattern where the population size increases rapidly without any limits.

Front

What is the role of competition in population dynamics?

Back

Competition for resources can limit population growth and lead to natural selection.

Front

What is the significance of birthrate in population studies?

Back

Birthrate influences population size and can indicate the health of a population.
