Algae: The Basics

Algae are diverse aquatic organisms that perform photosynthesis, similar to plants, using sunlight to produce energy. They can range from tiny, single-celled forms to large seaweeds. Algae are essential to aquatic ecosystems, providing oxygen and serving as the base of the food chain for marine and freshwater life. They also play a role in carbon dioxide absorption and nutrient cycling. Some algae are used in food, cosmetics, and biofuel production, while others can cause harmful algal blooms that impact water quality and health. Overall, algae are vital, adaptable organisms crucial to environmental health and industry.
