Marine ecosystems are among the largest of Earth's aquatic ecosystems. They include oceans, salt marsh and intertidal ecology, estuaries and lagoons, mangroves and coral reefs, the deep sea and the sea floor. They can be contrasted with freshwater ecosystems, which have a lower salt content. Marine waters cover two-thirds of the surface of the Earth. Such places are considered ecosystems because the plant life supports the animal life and vice-versa. See food chains.
The natural world sometimes has a magnificent way of dealing with its own problems – and this is exactly the case here. Coral threatened by toxic seaweeds emit a chemical signal which draws fish to eat away the danger. When Acropora nasuta corals come into contact with the toxic seaweed Chlorodesmis fastigiata, they scream for [...]
A new research from a team of international marine geoscientists has found that seagrass meadows, found in coastal regions, can store up to twice as much carbon as temperate or tropical forests. The scientists involved in the study, thus, believe that seagrasses can potentially become a viable solution to climate change, if scaled and preserved [...]
