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.
