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

• 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.
