Answer 1

The correct option is D

oceans

Oceans cover a large portion of the earth. The ocean is home to a large amount of organisms which include both producers and consumers. In oceans, microscopic organisms (e.g. cyanobacteria and dinoflagellates) along with multicellular producers (e.g. seaweed and seagrass) account for most of the $C{O}_2$ fixation on Earth.
