Aquatic Ecosystems: Rivers & Streams

Earth is sometimes called "the water planet". As such, marine ecosystems have a significant impact on the planet. For example, through photosynthesis, marine algae consume carbon dioxide (CO2) from the atmosphere and produce over 50% of the atmosphere's oxygen. Additionally, the evaporation of water from oceans eventually provides the majority of precipitation-rain and/or snow.
