A 10 meter by 10 meter plot of land has 25 trees on itWhat is the population density of the trees?

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

looks like the answer is     c     to me!

sorry to break it to ya but no one can answer your question it's just

jk but i am serious about the part that most people cant answer it beacuse you did not mention the section you are talking about. but it would if you added some detail and were a bit more specific.

i'd have to say the answer is probable the second option "the geosphere interacting with the atmosphere"
