Biodiversity

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

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

• Habitat Loss

• Invasive Species

• Replanting trees

• Pollution

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

Biodiversity refers to

• extinct species
• the variety of species on Earth
• nonrenewable resources
• the rate of species decline

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 cause native animals to relocate
• Non-native plants are able to be used for medicine
• Non-native plants compete with native plants for resources

What effect will an invasive species have on the carrying capacity of an ecosystem?

• The carrying capacity will increase
• The carrying capacity for everyone will decrease
• The carrying capacity will only decrease for those in competition for same resource
• The carrying capacity for all animals will stay the same

Kudzu has overgrown many parts of southern Missouri and native ground plants have disappeared from the area. This is an example of:

• Parasitism between kudzu and the native plants
• A predator prey relationship between ground plants and kudzu
• Competition occurring between the native and invasive species
• Commesalism occurring between the kudzo and native plants

How did the zebra mussels end up in the Great Lakes?

• In ballast tanks of ships
• They were intentionally released
• They have always been in the Great Lakes
• That's not a zebra mussel
