The United States is fortunate compared to China because _____________.
the U.S. is more dependent on grain-fed animals.
China's population has stabilized and the country is no longer growing.
it has more plentiful rainfall.
,it has a relative excess of cropland compared to population - ANSWER>>it has a relative excess

being studied. True or false? - ANSWER>>false

refers to a process by which producers of large quantities of carbon dioxide pay for
preservation of trees and other vegetation to sequester carbon.
is the amount of water left in the soil after gravity has removed what it can.
is a parasite that weakens a plant before making it more vulnerable to attack by other
oganisms. - ANSWER>>refers to a collection of ecosystems with similar components.
