The term "seaweed" is a general term used to describe a wide variety of non-vascular aquatic plants, or algae. seaweed uses sunlight, carbon dioxide and water to create food. For this reason, seaweed must grow near the ocean's surface.
sea turtles need food such as seaweed, crabs and other fish. They also need shelter and a sandy beach to lay their eggs. They need water and to maintain their body temperature which is easy for them beacause they live underwater.
Seaweed do not have to live in water all the time - think of inter-tidal periods when they are not in the water. Only some kinds of moss live in the water. Many kinds of mosses never live in the water - but do tend to live in a damp environment. The underlying concept to think about is dessication.
