Explanation:

Economic uses of algae are diverse. Via photosynthesis they perform half of the total carbon dioxide-fixation on earth, acting as the primary producers in aquatic habitats.

(1)Food source: Most species of marine algae are edible, such as Porphyra, Sargassum and Laminaria. Chlorella and spirulina are protein-rich. They are thus used as food supplements.

(2) Commercial importance: Agar is used in jelly and ice-cream preparations. Arar is derived from Gracilaria and Gelidium. Carrageenine is used in chocolates, paints, and toothpaste as an emulsifier. Its source is red algae.

(3) Medicines: Lots of red algae like Corallina are used to treat worm infections.
