Outline
Algae are a large and diverse group of organisms that use the sun’s energy to grow through photosynthesis. They occur naturally and are an essential component of a healthy aquatic ecosystem; however, an overgrowth of algae can be harmful. Scientists estimate that there are hundreds of thousands of different algae species. This video introduces six major types of algae that differ in their appearance, where they grow, the production of toxins, and the formation of algal blooms.
