I think it's oxygen and water because they are the substance for cellular respiration.
Frequent use of pesticides
The answer is c. oxygen.
Cellular respiration includes glycolysis, link reaction, Krebs cycle, and electron transport chain (ETC), in that order. The main function of ETC is a production of ATP. In this series of oxidation-reduction reactions, electrons from the previous stages of cellular respiration are taken and transported to the oxygen which is the final acceptor of electrons. As the result, water and ATP are produced.
I believe it’s cover crops but i could be wrong hope it helps
