Define population and community.

population all the inhabitants of a particular town, area, or country.

Explanation:

community is a group of people living in the same place or having a particular characteristic in common.

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.
