Causes of Biodiversity loss

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

All of the following are causes for biodiversity loss, EXCEPT:

• Habitat Loss

• Invasive Species

• Replanting trees

• Pollution

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

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

• Pollution

• Invasive Species

• Climate Change

• Overharvesting

4. Describes the gradual loss of a specie or population within a specific period of time.

• Species diversity

• Species reproduction

• Species extinction

• Species

5. A population of a specie is said to be extinct when (You may select more than one)

• When the resources of the specie in its ecosystem is fully consumed.

• When the last of the remaining specie has died out.

• When the remaining population of the specie could not reproduce anymore

• When there is water source within the habitat of the specie.
