Population and Demographics Flashcard

Front

What factors can affect population growth?

Back

Factors such as age at reproductive maturity, availability of resources, and environmental conditions can affect population growth.

Front

What are density-independent limiting factors?

Back

Density-independent limiting factors are factors that limit population growth regardless of population density, such as natural disasters or climate changes.

Front

What happens to population size when food is less available?

Back

Population size decreases due to limited resources.

Front

What is ecology?

Back

Ecology is the branch of biology that deals with interactions among organisms and their environment.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals an environment can sustain.

Front

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

Back

Density-dependent factors affect population growth based on population density, while density-independent factors affect growth regardless of density.

Front

How does age at reproductive maturity influence population growth?

Back

Earlier age at reproductive maturity can lead to faster population growth as individuals reproduce sooner.

Front

What role do weather conditions play in population dynamics?

Back

Weather conditions can influence resource availability and habitat suitability, affecting population growth.

Front

What is logistic growth?

Back

Logistic growth is a model of population growth that shows how populations grow rapidly at first and then level off as they reach carrying capacity.

Front

What is exponential growth?

Back

Exponential growth is a model of population growth where the population increases rapidly without any limiting factors.
