The study of algae is known as phycology (phycos = seaweed). Habit and Habitat . The non-fungal part is known as photobiont that contains chlorophyll. Algae also form a component of periphyton, which not only provides natural food for fish and other aquatic animals but is actively promoted by fishers and aquaculturists as a means of increasing productivity.
