Oceans can be found all around the world 75% of the planets surface is consumed by oceans The four main oceans are the Pacific, Atlantic, Indian, and Arctic

Important Producers are Kelp, Seagrass, and Algae Phytoplankton are the main photosynthesizers Phytoplankton have chlorophyll to capture sunlight, and they use photosynthesis to turn it into chemical energy

Zoo plankton- eat phytoplankton and are consumed by larger animals Green sea turtles- herbivores, they have a vegetarian diet of sea grasses and algae Manatees – eat a wide variety of vegetation Fish- omnivores, they eat plants and smaller fish Shrimp- omnivores, they eat plants and small animals

Whale- eat krill, plankton, fish and squid Octopus- eat crabs, fish and turtles Dolphin-eat fish and squid

Shark- eat fish, squid, other sharks, and marine mammals ( like sea lions, seals, and small whales) Killer Whales- eat fish, squid, sharks, seals, sea turtles and octopi

Oceans provides food in the form of fish and shellfish Transportation for ships Oceans are mined for minerals (salt, sand, gravel, and some manganese, copper, nickel, iron, and cobalt can be found in the deep sea) and drilled for oil

Oil spills- happening in the gulf coast POLLUTION-The Ocean is the worlds biggest dumping ground Over fishing – will eventually lead to extinction

The manatees are endangered because of pesticides and motor boats. A human is a predator to a manatee. Hunters kill manatees for meat, oil and blubber Coral Reefs- these organisms are declining due to the toxins humans are using to stun the fish
