The correct answer is (B) chemosynthesis and marine snow are the two ways that organisms on the bottom of deep sea food chains acquire energy.
What is the meaning of chemosynthesis and marine show?
Chemosynthesis is the utilization of energy supplied by inorganic chemical processes to make food in bacteria and other organisms. To generate a sugar, all chemosynthetic organisms require energy provided by chemical processes, although various species employ different methods.
Marine snow is a shower of biological particles that falls from the upper ocean to the deep sea. Marine snow refers to biological material that descends from higher in the water column. Some flakes fall for several weeks before reaching the ocean floor.
