Dugongs are animals that live in the ocean and eat underwater grasses. The sun is shining on the shallow ocean water where the grasses and dugongs live. What is happening to the carbon in the water around the grasses and the dugongs? Is carbon moving into the water, moving out of the water, or both? Carbon is not moving into the water; it is only moving out of the water. With this information, there is no way to know for sure. Carbon is moving into the water and out of the water, at the same time. Carbon is only moving into the water; it is not moving out of the water.
