Imagine you are listening to a series of student presentations in which the speakers hypothesize about the kinds of marine life they would expect to find in an abyssal marine zone. which hypothesis do you find most compelling?
question 16 options:

autotrophic organisms like seaweed and plankton will be common, along with many larger organisms supported by these producers.

coral reefs and high species diversity are expected, with many kinds of fish and invertebrates.

large open-ocean fish will live there, like tuna, marlin, and sharks.

low species diversity is predicted, except around hydrothermal vents where bacteria, fish, and crabs live.

The correct option is D. Low species diversity is predicted, except around hydrothermal vents where bacteria, fish, and crabs live.

Explanation:

Abyssal zone can be described as the deepest zone of an ocean. This zone receives minimal or no light of Sun at all. This means that the survival of producers i.e plants and algae here is impossible. There only very few animals which survive in this area. These organisms have to be dependent on other animals for food sources. As a result, the population of plants and animals  is very scarce in this zone. Mostly microorganisms such as bacteria are able to survive in this zone.
