4 The important thing about the ocean s ecosystems how plants and animals interrelate. The ocean is a habitat for many plants and animals!

5 tide pools. Some live in Some live in coral reefs. Some live in the open oceans, and some live far beneath. But, the most important thing is the interrelationships of plants and animals.

7 Sharks, polar bears, and orcas depend on a steady diet of seals. People use sharks, whales and seals for food and many products such as; lipstick, medicine and clothing.

14 Great White Sharks live in the ocean and occasionally dive deep into the ocean water. They can sometimes be found in water as shallow as three feet deep--about the height of a Kindergartner s shoulders.

15 Great White Sharks use their gills to breathe. They have a dorsal fin on their backs to help with balance as they swim. They swim by moving their tail left and right.

16 Wow! Sharks can open their mouth as wide as their head! More amazing Great Whites can open their mouths almost 4 feet wide and push their jaws outside their mouth for maximum bite!

17 Great white sharks are called apex predators. (They eat anything they want and nothing eats them!) Young great white sharks eat fish and other sharks. Whereas, an adult eats sea lions, seals, otters, sea turtles, and small whales.

20 Orcas, or killer whales, live in the ocean. In dark waters, orcas make special clicking sounds. Then they listen to the way the sounds echo back. This helps them find food and navigate.

21 mammals. They breathe Orcas are through a blowhole on the top of their head. Orcas have lungs like cats, dogs, and people. An orca can hold its breath for ten minutes or longer!

22 FLUKES, up and down for Orcas move their tails, called powerful swimming. They use flippers to steer and to turn.

23 There are two types of whales. The Orca is a toothed whale. They eat fish, squid, sharks, birds, seals, sea turtles, octopi, and even other whales.

24 Orcas live in small groups called pods. Like a family the pod members hunt, eat, and protect one another. But, the most important thing is the interrelationships of plants and animals.

25 The important thing about the ocean s ecosystem is how plants and animals interrelate. The Blue Whale lives in the ocean and is the largest animal to ever live on Earth.

26 mammals. They breath Blue Whales are through their two blowholes on the top of their head. Their spout goes up 30 feet high -- as tall as a telephone pole.

27 plankton and krill These enormous mammals eat tiny organisms like through their baleen. Baleen is a stringy curtain hanging down in their mouth. Tiny shrimp called krill stick to the baleen. They have a special body designed with pleated throat

28 grooves, allowing for expansion. Their throat gets bigger and bigger to hold a large amount of water. Then the whale closes it s mouth, spits out the water, and licks off the attached krill in the baleen.

29 social and also live in pods. Blue Whales are very Group living is safer when enemies like sharks and killer whales are nearby. But, the most important thing is the interrelationships of plants and animals.

30 The important thing about the ocean s ecosystem is how plants and animals interrelate. home to many other plants Oceans are and animals. An ecosystem is a place where animals and plants depend on their environment,

31 and the environment depends on them. OCEAN ECOSYSTEM has six An parts. The sun is the first part of the ecosystem providing heat and light.

32 The second part of the ecosystem are nonliving things such as water, sand, rocks and minerals.

33 Next are the producers like kelp, phytoplankton and algae who make food and oxygen to support the ecosystem.

34 Then the primary consumers like baleen whales and mussels eat the producers.

35 The secondary consumers like sharks, sea anemones and humans, who hunt their food, eat primary consumers.

36 Finally you will find the decomposers such as bacteria and lichen breaking down dead things and helping to start another food chain. But, the most important thing is the interrelationships of plants and animals.
