Ch. 7 Biodiversity

Front

What is genetic diversity?

Back

Genetic diversity refers to the variety of genes within a species, which allows for variations in traits and adaptations to different environments.

Front

What is an endangered species?

Back

An endangered species is a species that is at risk of extinction due to a rapid decrease in population or habitat loss.

Front

What does it mean for an ecosystem to be stable?

Back

An ecosystem is considered stable if it is both resistant (able to withstand disturbances) and resilient (able to recover from disturbances).

Front

What is species richness?

Back

Species richness is the number of different species present in a given area, which contributes to the overall biodiversity.

Front

What is the difference between threatened and endangered species?

Back

A threatened species is likely to become endangered in the near future, while an endangered species is at immediate risk of extinction.

Front

What is ecosystem diversity?

Back

Ecosystem diversity refers to the variety of ecosystems within a particular area, including different habitats, communities, and ecological processes.

Front

What is the significance of biodiversity?

Back

Biodiversity is crucial for ecosystem stability, resilience, and the provision of ecosystem services such as clean air, water, and food.

Front

What are invasive species?

Back

Invasive species are non-native species that spread rapidly in a new environment, often causing harm to native species and ecosystems.

Front

What is the relationship between biodiversity and ecosystem services?

Back

Higher biodiversity typically leads to more robust ecosystem services, as diverse ecosystems are better at providing resources and maintaining ecological balance.

Front

What is the impact of human activity on extinction rates?

Back

Human activities, such as habitat destruction, pollution, and climate change, have significantly increased extinction rates beyond natural levels.
