Detailed explanation-1: -Because kelp attaches to the seafloor and eventually grows to the water’s surface and relies on sunlight to generate food and energy, kelp forests are always coastal and require shallow, relatively clear water.

Detailed explanation-2: -These dense canopies of algae generally occur in cold, nutrient-rich waters. Because of their dependency upon light for photosynthesis, kelp forests form in shallow open waters and are rarely found deeper than 49-131 feet .

Detailed explanation-3: -Kelp grows at or below the low-tide level on the rocky seabed and extends to depths as far as sunlight can penetrate. Seaweed doesn’t have a vascular system like other plants, but all parts of the kelp absorb the nutrients and gases that it needs to grow from the water in which it is immersed.

Detailed explanation-4: -The main result of this study is that kelp abundance is modified by the combined impact of depth, waves and currents, and that dense kelp forests are found mainly in relatively shallow and flat terrain in wave exposed and low current areas.

Detailed explanation-5: -Kelp are large brown algae (Phaeophyta) that live in cool, relatively shallow waters close to the shore. There are about 30 different species of kelp worldwide.
