How are the plants in a desert ecosystem most likely to differ from the plants in a rain forest ecosystem?
erik [133]
Hey,

I believe this answer is A: The desert plants are likely to be better at retaining water.

Which they do, and they have to cause water is very scarce in the desert unlike the rain forest.

Desert plants likely to be larger is not proven and most plants can vary in size.

Hope this helps!
Brainliest is always appreciated if you feel its deserved.
