The ocean is a very large ecosystem on the earth. It covers around 71% of the earth’s surface and produces about half of the earth’s oxygen. It holds plenty of salt water, and the water falls onto the land and then rises to the sky, and then returns to the ocean. This goes on and on, so the ocean is just like the “heart” of the earth.
