the plants absorb sunlight with the stomata and it undergoes the process of photosynthesis with carbon dioxide which was produced from human and other animals, the end product of that is the oxygen and glucose (sugar)
Photosynthesis is a process in which light energy is converted into chemical energy i. e. glucose which is a type of monosaccharide. In photosynthesis reaction, plant take water from the soil and carbondioxide from the surrounding air. When these two substances combine in the presence of sunlight produces oxygen and glucose. Oxygen is released in the atmosphere and glucose is stored in different parts of plant body.
Because the salt water's density and the ship's density are very different (compared to fresh water and the ship's density) It will allow the ship to remain seated higher in the water than when the ship is in fresh water.
