Carrying Capacity and Limiting Factors Review

Front

What is carrying capacity?

Back

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

Front

What are limiting factors?

Back

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

Front

What is logistic growth?

Back

A pattern of population growth that starts exponentially but slows as the population reaches carrying capacity due to limited resources.

Front

What happens when a population exceeds its carrying capacity?

Back

The population may experience a decline due to resource depletion, increased competition, or other limiting factors.

Front

What is the difference between biotic and abiotic limiting factors?

Back

Biotic factors are living components (like predators and food), while abiotic factors are non-living components (like temperature and water availability).

Front

How does competition affect population growth?

Back

Competition for limited resources can slow population growth and may lead to a decrease in population size.

Front

What is an example of a density-dependent limiting factor?

Back

Disease, which spreads more easily in crowded populations.

Front

What is an example of a density-independent limiting factor?

Back

Natural disasters, such as floods or wildfires, that affect populations regardless of their density.

Front

What does a cyclical population growth pattern indicate?

Back

It shows that populations rise and fall over time, often in response to changes in resources or predation.

Front

What is the significance of the carrying capacity in ecology?

Back

It helps ecologists understand the balance between species and their environment, guiding conservation efforts.
