Rockweed

I'm researching rockweed for this project. Rockweed is a type of large brown algae that lives on rocky shores by attaching itself to the rocks. It does not have real roots, stem, or leaves, but it absorbs nutrients from the water and from the sun through its leaf-like blades. Unlike some algae rockweed has a high tolerance to temperature, but also a great need for sun light. Rockweed is important to its ecosystem because it maintains the quality of the water where it is located. It removes metals and some nutrients to help maintain the water quality, as well as converting inorganic matter into organic which benefits animal life in the area. http://www.rockweedcoalition.org/downloads/Functions_and_Values_of_Rockweeds_ME_DEP.pdf
