APES Final Review Unit 2: Biodiversity

Front

What is a population in ecological terms?

Back

A population is all individuals of the same species occupying the same area.

Front

What is the likely consequence of increasing mean global temperatures on specialist species?

Back

Specialist species living in fragile ecosystems will risk extinction.

Front

What type of service does the aesthetic value of an ecosystem provide?

Back

The aesthetic value of an ecosystem provides a cultural service.

Front

What are ecosystem services?

Back

Ecosystem services are the processes by which life-supporting resources are produced.

Front

What prediction can be made about island biogeography?

Back

Animals will migrate successfully to islands closer to the mainland, leading to more diversity.

Front

Define biodiversity.

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem.

Front

What is the significance of genetic diversity within a population?

Back

Genetic diversity increases a population's ability to adapt to changing environments.

Front

How does habitat fragmentation affect biodiversity?

Back

Habitat fragmentation can lead to decreased biodiversity by isolating populations and reducing genetic diversity.

Front

What is the relationship between ecosystem stability and biodiversity?

Back

Higher biodiversity generally contributes to greater ecosystem stability and resilience.

Front

What role do keystone species play in an ecosystem?

Back

Keystone species have a disproportionately large impact on their ecosystem relative to their abundance.
