Answer 1

I believe that would be: A. "The decomposition of marine plants that depletes dissolved oxygen"

Answer 2

The correct option is A.
Decomposers are living organisms which feed on dead organic matters in order to break them down. Decomposition of dead organic matter occur both on land and in water. In the aquatic environment, decomposition of organic matter usually deplete the quantity of oxygen in the water.
