Biodiversity Review

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the diversity of species, genetic variation, and ecosystem diversity.

Front

What are invasive species?

Back

Invasive species are non-native organisms that, when introduced to a new environment, can outcompete native species for resources, disrupt ecosystems, and cause ecological harm.

Front

What is population growth?

Back

Population growth is the increase in the number of individuals in a population, often leading to increased demand for resources and potential environmental strain.

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 its population or habitat.

Front

What is habitat loss?

Back

Habitat loss occurs when natural habitats are destroyed or altered, often due to human activities, leading to a decline in biodiversity.

Front

What is over-exploitation?

Back

Over-exploitation refers to the unsustainable use of natural resources, such as overfishing or excessive logging, which can lead to species decline.

Front

What is pollution?

Back

Pollution is the introduction of harmful substances or contaminants into the environment, which can negatively impact ecosystems and biodiversity.

Front

What is a keystone species?

Back

A keystone species is a species that has a disproportionately large effect on its environment relative to its abundance, playing a critical role in maintaining the structure of an ecosystem.

Front

What is an endemic species?

Back

An endemic species is a species that is native to a specific geographic area and is not found naturally anywhere else.

Front

How do invasive species affect native ecosystems?

Back

Invasive species can disrupt food webs, outcompete native species for resources, and alter habitat structures, leading to declines in native biodiversity.
