The Kelp Forests are very different from the other habitats. The kelp forest is a forest, but it is not a forest of trees. It is made of seaweed called giant kelp.
Giant kelp grows in cool coastal waters where sunlight can go down to a rocky sea floor.
Kelp needs sunlight in order to grow. It also needs a hard surface to grow on. The holdfast is a part that attaches the kelp to the ocean floor. The blade is the leaflike part that takes in sunlight to make food. The stipe is the part that connects the holdfast to the blade.
