Algae are photosynthetic microorganisms that perform photosynthesis and produce oxygen (O2) and consume carbon dioxide (CO2) from the atmosphere. During photosynthesis, algae produce at least half of the oxygen in Earth’s atmosphere. Most of the algae inhabit the aquatic environment, either freshwater or marine habitats. They can also occupy on rocks, soils, vegetation, or moist … Read more

All living organism needs energy to perform their different normal metabolic functions. Food is the source of energy of the living body. Photosynthesis is the process by which the chlorophyll-containing green plant and algae synthesizes glucose (carbohydrates) and evolves oxygen using CO2 of the air and water in the presence of sunlight. During the photosynthesis, … Read more
