Population Ecology Practice Test

Front

What is population ecology?

Back

The examination of how populations interact with the environment and each other.

Front

What occurs during exponential growth in a population?

Back

The population grows increasingly faster.

Front

What is a logical prediction for fox populations when rabbit populations decrease due to disease?

Back

The number of foxes will decrease because their main food source is less available.

Front

Which factors affect population size?

Back

Immigration, emigration, birth rate, and death rate.

Front

How do density-dependent factors impact populations?

Back

They have an increasing effect as population size increases.

Front

What are density-independent factors?

Back

Factors that affect populations regardless of their density.

Front

Define carrying capacity in an ecosystem.

Back

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

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

What role do predators play in population dynamics?

Back

Predators help control the population size of prey species.

Front

What is the significance of immigration in population ecology?

Back

Immigration increases the population size by adding new individuals.
