Question

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.

Answer 1

Answer:

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

Explanation:

The abyssal zone can be described as the deepest layer of an ocean. This area does not receive any of the Sun's light and hence it supports very little life. The organisms that live here cannot survive on producers fro food as there are no plants which grow here. Hence, the organisms in this area feed on each other for food which makes the population even more scarce. However, some kinds of microorganisms survive in this kind of atmosphere.
