01-06 Population Dynamics

Front

What is carrying capacity?

Back

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

Front

What happens when a population exceeds its carrying capacity?

Back

The death rate may rise due to increased competition for resources.

Front

What are two ways a population can decrease in size?

Back

Decreased birth rate and emigration.

Front

What is emigration?

Back

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

Front

What is immigration?

Back

The act of entering a new population from another area.

Front

What is a quadrat?

Back

A tool used in ecology to sample the quantity of organisms in a specific area.

Front

What factors can affect population growth?

Back

Birth rate, death rate, immigration, and emigration.

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are living components of an ecosystem, while abiotic factors are non-living components.

Front

How does a high birth rate affect population dynamics?

Back

It can lead to rapid population growth if resources are available.

Front

What role does competition play in population dynamics?

Back

Competition for resources can limit population growth and lead to increased mortality.
