Image "B" shows more biodiversity than image "A". Why?

• Because "B" shows more different species than image "A"

• Because image "B" has less different species than "A"

• "A" has a greater number of same species plants so this statement is wrong.

• Both images show the same biodiversity

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

• If one organism is removed the food web can still operate (work) with less of a negative effect.

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

Food Web B is an example of...

• Low biodiversity and low sustainability. If the producer dies then all the food web will suffer.

• High biodiversity and high sustainability. If an organism is removed the food web will continue with no effect.

Soccer fields are most often made of one single type of grass. What type of biodiversity do sports fields show?

• High "Rich" biodiversity because there is only one type of producer.

• Low "Poor" biodiversity because there is only one type of producer.

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.
