Answer :
Final answer:
These organisms are found in the benthic zone, which is rich in nutrients from dead organisms that have sunk to the ocean floor. Photosynthetic organisms are found in areas where sunlight is available, such as the photic zone, intertidal zone, neritic zone, and parts of the oceanic zone.
Explanation:
These organisms that feed on dead organisms sinking from above and receive no sunlight are typically found in a nutrient-rich portion of the ocean known as the benthic zone. This zone extends along the ocean bottom from the shoreline to the deepest parts of the ocean floor, and it is characterized by its accumulation of sand, silt, and dead organisms, making it a hotspot for diverse life forms, including sponges, sea anemones, marine worms, sea stars, fishes, and bacteria, despite the lack of sunlight.
When considering where you might expect to find photosynthetic organisms in various oceanic regions, they would typically be found in areas where sunlight can penetrate, facilitating photosynthesis. Such regions include the photic zone, the intertidal zone, the neritic zone, and parts of the oceanic zone that are shallow enough for sunlight to reach. The aphotic zone, abyssal zone, and benthic realm typically do not support photosynthetic life due to the absence of sunlight.
