Causes of Decreased Biodiversity

This is the disappearance of a particular population from a given area, but not the entire species globally.

• extinction

• extirpation

• evacuation

• evaluation

This is the extinction of a species one by one, not a sudden loss of many species

• background extinction

• mass extinction

• fragmentation

• biotic potential

This classification of risk means that the species is at serious risk of extinction.

• threatened

• vulnerable

• endangered

• extinct

The status of a "threatened species" means:

• they are almost extinct

• they are likely to become endangered

• they are extinct

• their numbers are increasing

When taken to a new habitat, non-native plants often threaten native plants of the new habitat. Why do they do this?

• Non-native plants are able to mutate rapidly

• Non-native plants are able to be used for medicine

• Non-native plants cause native animals to relocate

• Non-native plants compete with native plants for resources

Forest clearing, farming, and road building are all examples of

• Biodiversity

• Population distribution

• Habitat loss

• Climate Change

All of the following describe habitat fragmentation, EXCEPT:

• Gaps form within a habitat

• Patches of suitable habitat are surrounded by unsuitable habitat

• Often a result of habitat loss

• Increases the number of species

• Habitat loss and change

• Climate Change

• Invasive species

All of the following affect biodiversity only in certain locations and times, EXCEPT:

• Pollution

• Invasive Species

• Climate Change

• Overharvesting
