| Algae are capable of living in habitats where few other organisms could survive. They can live in virtually any habitat in which there is sunlight and adequate moisture. Algae are found in freshwater lakes, ponds, streams, swamps, on moist soil, wood, and throughout the sunlit zones of the marine environment, as well as on the snowfields and glaciers of Antarctica (left) and in thermal hot springs at Yellowstone National Park (right). |
