Question

what are the two ways that organisms on the bottom of deep sea food chains acquire energy? a. photosynthesis and chemosynthesis b. chemosynthesis and marine snow c. marine snow and photosynthesis d. chemosynthesis and predation please select the best answer from the choices provided

Explanation:

In deep - sea environments, sunlight is scarce, so photosynthesis is not a common energy - acquisition method. Chemosynthesis is used by some bacteria to convert chemical energy into organic compounds. Marine snow, which consists of organic matter falling from upper layers, can be consumed by organisms. Predation also occurs among deep - sea organisms for energy.

Answer:

B. chemosynthesis and marine snow
