Population Dynamics Review

Front

What is carrying capacity?

Back

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

Front

What does a J-shaped curve in population growth indicate?

Back

It indicates exponential growth, where the population increases rapidly due to unlimited resources.

Front

What does a population pyramid with a wider base indicate?

Back

It indicates a higher number of young individuals, suggesting a growing population.

Front

What is logistic growth?

Back

A pattern of growth where the population increases rapidly until it reaches carrying capacity, resulting in an S-shaped curve.

Front

What does a population pyramid with a narrower base suggest?

Back

It suggests fewer very young children in the population.

Front

What is the difference between exponential growth and logistic growth?

Back

Exponential growth occurs with unlimited resources, while logistic growth occurs when resources are limited, leading to a carrying capacity.

Front

What factors can affect carrying capacity?

Back

Food availability, habitat space, water supply, and environmental conditions.

Front

What is a population pyramid?

Back

A graphical representation of the age and sex distribution of a population.

Front

What does it mean if a population is stable?

Back

The number of births and deaths are roughly equal, leading to little change in population size.

Front

What is the significance of a population's age structure?

Back

It helps predict future population growth and social needs.
