Ecology Quiz 2

What is the difference between biotic and abiotic?

• Biotic are non-living things
• Abiotic are living organisms
• Biotic is life,
  Abiotic is non-living
• Biotic is non-living, Abiotic is living

What does biodiversity mean?

• Only one species in an area.
• The different amount of species in an area
• All abiotic life
• Nitrogen fixation

Biodiversity is important to keep an area (biome) healthy. In this example "Food Web A" is sustainable. Why is sustainability important for an ecosystem in "Food Web A".

• If one organism is removed the food web can still operate (work) with little or no negative effect.

• If an organism is removed the food web will collapse and will affect the environment.

Great Biodiversity = Great Sustainability

• True

• False

In this food web example you can see that rain forests have many producers consumer and predators. How would you describe the rain forest biome?

• It has high "rich" biodiversity

• It has low "poor" biodiversity.

Biodiversity is best described as...

• the amount of different species of organisms (plants and animals) living in the same area.

• when only a few species inhabit an area.

• when only one organism (plants and animals) is found living in one area.

Why is "A" less biodiverse than "B"?

• Image "A" is more biodiverse.

• Image "A" has many corn plants and this makes it have high "rich" biodiversity.

• Image "A" has a lot more plants than image "B"

• Even though "A" has a lot of corn plants they are all the same species and makes this a low "poor" biodiverse area.

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. 

This picture is a great example of ____________ biodiversity.

• high
• moderate
• low
• hhhmmmm there is no way to know without counting.
