Interdependence in the ecosystem means

that….• Interdependence in the ocean ecosystem means

that an living thing depends on something to live and survive. It could be symbiotic relationship so for example they could get shelter, protection or food.

Symbiotic RelationshipIsopods and fish• The isopods is a parasite

that eats the fish’s tongue and getting the first bite of everything the fish consumes. This relationship is called parasitism because the isopod gets a benefit but the fish gets a negative impact.

Symbiotic RelationshipRemora fish(sucker fish) and manta ray• Remoras are known as the suckerfish.

They attach themselves to many different types of species, like dugongs, sharks, sea turtles, and manta rays. The remora uses its host for protection, transportation, and scraps from the larger predator’s meals. The Relationship between remora fish and manta ray is mutualism because both of them gets a benefit. The parasite gets a meal from the manta ray and the manta ray gets cleaned by the sucker fish from bacteria and dirts.

Interdependence Between Humans and

Living Things• The interdependence happen is between

fisherman and fish. The fisherman need fish to survive because without fish they can’t get any money and if they don’t get any money they can starve.

Interdependence between Humans and Non-Living

Thing• The interdependence between humans and non

living things is between people that make salt and salt water. The people that make salt need salt water to make salt and they can sell it to restaurants so they can get money. Another example is between someone that sells seashells and the seashell on the beach. Many people in Bali sells painted and decorated seashells in the market and the people that sells seashells need the sea shell to survive because they need money and by selling they can get money for food and other stuffs they need for living.

Problems HappenOver fishing and destructive method of fishing• Some people were overfishing and the reason is

the more fish the money the fisherman gets. Some people also use destructive method such as using bombs,  bottom trawling which destroys sea floor habitat and scoops up many unwanted fish and animals. This problem has a serious impact to the ocean ecosystem because fish are interdependent to other animals and it may cause the predator starve and other animals that eat fish too.

Problems HappenPollution • Some people are littering in the beach so the Bali

sea will be affected and the water will get polluted. There is many tourist that come to Bali and some of the may throw rubbish in the water. The polluted water can cause the fish die.

Problems HappenBusy Transportation• There is a lot of tourist that go to Bali for holidays or

vacation. Many of the tourist have fun with jets skis, boats and parceling. The boats can destroy the coral reefs because of the propeller and the force that the propeller make. It can destroy the plants, coral reefs and even kill the fish. Jet Ski does not use propeller but it uses Jet system. The jet system blow out really strong air so it can move the jets ski. The really strong air can wipe out the plants and coral reef. People also use yacht to travel from different island with really heavy loads like truck and cars. The yacht have a really big and strong propeller and it can destroy the ocean ecosystem and habitat.

Actions We Can Do• We can reduce the use of plastics. So when we

are in the supermarket we can use a box or canvas bag instead other than plastic bags. We can use it but we need to recycle and try to not use too much. So for example we don’t ask for separate plastic bags when we are in the supermarket or other shopping places such as malls. What if our Bali beach was as clean as the beach in the background wallpaper?

Actions We Can Do• We can tell info to our friends so that when they

go to Bali they can do the same action and help the ocean ecosystem. They also can know how the system works and all the important information about ocean ecosystem in Bali.

Actions We Can Do• Bali has the best seafood and it is in the Jimbaran

beach. We can help the ocean ecosystem by trying to eat less seafood so there will be less fish consumed and killed only for the seafood.

Best Action• The Best Action that I choose is to present and

tell this power point and information to my friends so that they can understand and they also can do the actions. They also can know the impacts and the problems too.
