Biological Diversity Review #1

Which region of the globe has the highest biodiversity?

• equator

• North Pole

• South Pole

• None, biodiversity is equally distributed

As you increase the latitude (get closer to the poles), what happens to the biodiversity?

• increases

• decreases

• does not change

Why is biodiversity in an ecosystem so important?

• Because it can help humans where to determine good places to develop farm land.

• Because places that have a healthy biodiversity are unaffected by major disturbances.

• Because having a high biodiversity allows ecosystems to withstand major changes.

• Because having a high biodiversity allows for fewer opportunities of competition for similar resources.

High biodiversity is 

• having a lot of the same organism.
• having a few of the same organism.
• having a lot of variety of different organisms.
• only having one of each organism. 

Which shows more biodiversity Image A or Image B. Why?

• Image B is more biodiverse, because shows more different species than image A.

• Image A is more biodiverse, because shows a greater number of organisms that image B

• Both images show the same biodiversity

Which habitat has the highest species richness?

• A

• B

• C

• More information is needed

Which statement best describes an example of low species diversity?

• A population of frogs has a wide variety of skin colors

• A marsh ecosystem is covered by a single species of cattail bulrushes

• A state park includes multiple forest, wetland, and freshwater ecosystems

A group of organisms that are similar enough to be in the same category that can reproduce together to pass on their genes.

• Organism

• Species

• Breed

Wild cats of Africa are an example of

• diversity within species

• diversity between species

These moths are all the same species. The differences between their wings is an example of ________________

• diversity within species

• diversity between species
