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.

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

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.
