Acid rain and other forms of pollution can cause soil acidification, which decreases the number of decomposers in the soil. what is most likely to happen to an ecosystem that experiences soil acidification? a. the level of energy available in the ecosystem would increase, which would cause the population of autotrophs to increase. b. the level of available nutrients in the soil would decrease, which would cause the population of producers to decrease. c. the population of primary consumers would increase because of increased production by autotrophs. d. the population of primary consumers would increase because of decreased competition from decomposers.
