Ecosystems and Extinction

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

• extinction

• extirpation

• evacuation

• evaluation

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

The living planet index

• tracks species decline

• lists all animal species in the world

• describes exponential growth

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

• Habitat Loss

• Invasive Species

• Replanting trees

• Pollution

How can humans best help an endangered species avoid extinction and protect biodiversity?

• they can feed the animals

• they can put the animals in a zoo

• they can protect the animal’s habitat or restore native habitats

• they can take the animal to new habitats

When does overharvesting (overhunting/poaching) occur?

• When factories produce air pollution

• when humans hunt, fish, or harvest a species faster than it can replenish its population

• When human populations increase rapidly, spread, and displace native species.

• when native species are reintroduced to an area
