Georges Bank is located off of Cape Cod, the Middle Atlantic Bight is located offshore of Virginia and northern North Carolina, and the Gulf of Maine is located off the coast of New England. Which of the following statements is the most likely reason for the productivity trends seen for the Gulf of Maine? e -Middle Atlantic Bight -Georges Bank-Gulf of Maine d O The area has fewer large predators like sharks. O The area has fewer animals that eat plankton. The area gets hit less by hurricanes so the ocean water mixes less. O The area gets more intense sunlight than the other areas.

Killer whale Crabeater seal Elephant seal Adelie penguin Squid Leopard seal Cod Small animals and protists Algae Krill In the food web above, there are eight food chains that include krill. In the space provided, identify all of the organisms in the order in which they occur in four of these eight food chains. 1. Chain 17. Describe the variety of phytoplankton and zooplankton in the sublittoral study site (Site C). How can you differentiate them? 8. Draw a diagram of the food chain which you think exist in the shore ecosystem that studied. What will happen if there is an extinction of one of the species especially you the ones at the top of the chain? 9. Based on all the aspects that you have observed, is the shore that you studied is polluted? If yes, what are the steps that could be taken? Give your comments.Explain Briefly what is SDG 14 – Life below Water SDG 15 – Life on Land and its importance.
