Feedback mechanisms are biological processes in which organisms can maintain (Response area). In (Response area) feedback mechanisms, the body will maintain a desired set point. An example of a this feedback mechanism is (Response area). In (Response area) feedback mechanisms, the body moves away from the desired set point. An example of this would be (Response area).

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.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high

the cost of mining is extremely low compared to the money earned from mining, creating income to improve the environment.
