Algae are producers. This means they produce their own energy, usually through photosynthesis. Like most producers, algae turn sunlight, carbon dioxide and water into glucose for energy.
Algae are primary producers of organic matter which animals depend on either directly or indirectly through the food chain (APHA, 1995) Typically, algae are autotrophic (derive cell carbon from inorganic carbon dioxide), photosynthetic (derive energy for cell synthesis from light), and contain chlorophyll. They are also chemotrophic in terms of nighttime respiration, e.g., metabolism of molecular oxygen (O2).
