What is captive breeding?

Back

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 ecological community.

Front

What is habitat preservation?

Back

Habitat preservation involves protecting natural environments to maintain biodiversity and the health of ecosystems.

Front

What are invasive species?

Back

Invasive species are non-native organisms that, when introduced to a new environment, can cause harm to native species, ecosystems, and human activities.

Front

What is extinction?

Back

Extinction is the end of an organism or a group of organisms, meaning that no individuals of that species remain alive.

Front

What is the economic value of biodiversity?

Back

The economic value of biodiversity includes benefits such as new medicines, tourism, and materials for clothing, but does not include harming keystone species.

Front

How does climate affect biodiversity?

Back

Generally, warmer and wetter climates support greater biodiversity due to more favorable conditions for a variety of species.

Front

What is bycatch?

Back

Bycatch refers to the unintentional capture of non-target species during fishing, which can lead to population declines in those species.
