state the source of carbon (iv) oxide in acquatic ecosystems

Answer 1

The primary source of carbon (IV) oxide, also known as carbon dioxide (CO2), in aquatic ecosystems is the atmosphere. CO2 is naturally present in the air and can dissolve into water bodies through processes such as air-water exchange and diffusion. Additionally, activities like respiration by aquatic organisms, decomposition of organic matter, and volcanic activity can also contribute to the release of CO2 into aquatic ecosystems.
