　　In most parts of the sea, there are plenty of fishes and plants.4 Some live near the top of the sea. Others live deep down. There are millions of tiny living things that float in the sea. These floating things are so small that it is hard to see them Many fish live by eating these.   
　　The sea can be very cold. Divers, who go deep down in the sea, know this. On the top the water may be warm. When the diver goes downwards, the sea becomes colder and colder. Another thing happens. When the diver goes deeper, the water above presses down on him. It squeezes him. Then the diver has to wear clothes made of metal. But he cannot go very deep.
