Ocean Animals And Plants
Seventy percent of Earth's surface is water. There are four oceans: the Atlantic ocean, the Pacific ocean, the Indian ocean, and the Arctic ocean. They form one global ocean. The landscape of the ocean floor is different. There are mountains, volcanoes, and trenches six miles deep.
Ocean water is always moving. Waves do not show movement. Plants and animals live in the oceans. Seagrass grows in shallow waters. Animals such as fish and shrimp and whales also live in the ocean.
There is a reddish pink octopus who lives in a reef and eats small fish.

Brown seaweeds, which mostly grow in cold waters of the Northern Hemisphere, form a large and diverse group of marine algae. Some forms of brown seaweed, such as kelp, are a nutritious, traditional food source and are also available in supplement form. Numerous potential health benefits can be gained from taking kelp supplements.
Seagrass is grown in shallow water because it needs lots of sunlight. These plants live on the ocean floor. Seagrasses are marine flowering plants. There are about sixty species worldwide. Seagrasses photosynthesize and undergo submarine pollination. They complete their entire life cycle underwater. Different animals feed on seagrasses.
Kelp is a type of brown seaweed that grows in the ocean and can reach enormous sizes. It is a common ingredient in Asian cuisine. It has become a popular dietary supplement, mainly because of its iodine content. Some evidence indicates that kelp may help prevent infection from certain diseases.
Oil and sewage spills, chemicals, and metals kill all marine ecosystems. Turtles mistake plastic bags for jellyfish. Abandoned fishing nets entangle sea birds and sea mammals.
People throw garbage and sometimes animals eat it. Overharvesting killed many ocean animals, from whales to fish. The souvenir trade threatens coral reefs.
Sometimes people clean oceans. We need to come to better laws to stop ocean pollution.
