Subdivision of the PNS that controls voluntary activities such as the activation of skeletal muscles.
A. Autonomic Nervous system
B. Central Nervous System
C. Peripheral Nervous System
D. Somatic Nervous System

The peripheral nervous system (PNS) is divided into the somatic nervous system and the autonomic nervous system. The somatic nervous system (SoNS) is the part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles.

explanation:

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.
