Regarding tropical rainforests, the term evapotranspiration refers to the fact that
A. trees absorb carbon dioxide and "exhale" oxygen.
B. the humidity of rain forests can produce local and regional precipitation.
C. deforestation causes a decline in atmospheric oxygen.
D. deforestation causes a loss of soil fertility due to water evaporation
I think the answer to your question is c. deforestation causes a decline in atmospheric
oxygen because evapotranspiration means the process by which water is transferred
from the land to the atmosphere by evaporation from the soil and other surfaces by transpiration from plants.
