Final answer:
The neritic zone is rich in biodiversity and includes active swimmers like swordfish, dolphins, and sharks, which feed on plankton and smaller fishes, making the correct answer d. swordfish, dolphins, and sharks.
Step-by-step explanation:
The neritic zone of the ocean is characterized by waters that extend from the intertidal zone to about 200 meters (650 feet) at the edge of the continental shelf, where photosynthesis still occurs due to the penetration of light. This zone is rich in biodiversity and productivity thanks to its well-oxygenated waters, stable temperatures, and abundant phytoplankton. Considering these characteristics, the correct answer to which consumers live in the neritic zone is d. swordfish, dolphins, and sharks. These are considered nekton, which are aquatic animals that swim actively and feed on plankton or other nekton. They play a significant role in the food chain within the world's fisheries that exist predominantly within this zone.
