Global warming is causing sea levels to rise. A low-lying grassland on an island is now flooded by the sea more often than it used to be.
Which is the most likely effect on the grassland?
Each plant species quickly adapts to being flooded, so no species are lost from the grassland
Some plant species die out, but biodiversity stays the same because no animal species are lost
Plant species grow faster because the floods give them more water, so biodiversity rises
Plant species that cannot survive regular flooding die out, so biodiversity falls
