learning task 1 :
(1.) Phytoplankton and algae form the bases of aquatic food webs. They are eaten by primary consumers like zooplankton, small fish, and crustaceans. Primary consumers are in turn eaten by fish, small sharks, corals, and baleen whales.
(2.) Herons are carnivores that eat fish, small mammals, insects, crustaceans, and reptiles. Herons eat fish, frogs, small mammals, crustaceans, reptiles, and even other birds! Although you may not think of them as carnivores, herons stick to a diet mostly consisting of other animals!
(3.) When they're in the ocean, young and adult salmon eat a wide variety of prey, including:
When they're in the ocean, young and adult salmon eat a wide variety of prey, including:Fish such as capelin, Atlantic herring, sand lance, barracudina and lanternfish.

(4.) In turn, shrimp are eaten by various animals, particularly fish and seabirds, and frequently host bopyrid parasites.
(5.) Vertebrate predators of snails and slugs include shrews, mice, squirrels, and other small mammals; salamanders, toads and turtles, including the uncommon Blandings Turtle Emydoidea blandingii; and birds, especially ground-foragers such as thrushes, grouse, blackbirds, and wild turkey.
learning task 2
(1.) Hermit crabs are pretty easygoing about what they eat. In fact, they'll dine on just about anything they can find in the water that surrounds them, including small fish, invertebrates such as worms, plankton and any food particles that happen to be floating by.
(2.) algae
algaeThey attach themselves using mucus and a muscular "foot", which seals them against the rock and protects them from desiccation during low tide, and from high-energy waves action. Limpets eat by grazing on algae found on rock surfaces.
(3.) Phytoplankton and algae form the bases of aquatic food webs. They are eaten by primary consumers like zooplankton, small fish, and crustaceans. Primary consumers are in turn eaten by fish, small sharks, corals, and baleen whales.
(4.) Sea urchins will eat just about anything that floats by. Its sharp teeth can scrape algae off rocks, and grind up plankton, kelp, periwinkles, and sometimes even barnacles and mussels. Sea urchins are sought out as food by birds, sea stars, cod, lobsters, and foxes.
(5.) starfish, shore-birds, fish, seals
