Which statement correctly describes a chemical reaction?

What are the statements?

Explanation:

Chemical reactions are when the original material or substance(s) becomes something else. An example is combustion.

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.
