A marine habitat refers to the environment found in oceans and seas, where various forms of life thrive. This habitat includes diverse ecosystems such as coral reefs, mangroves, and deep-sea environments. Marine habitats are crucial for supporting a wide range of species, including fish, mammals, and invertebrates, all of which play important roles in the ocean's food web. These habitats are characterized by factors like salinity, temperature, and light availability, which influence the types of organisms that can live there. For example, coral reefs provide shelter and food for many marine species, while mangroves serve as nurseries for young fish. Protecting marine habitats is essential for maintaining biodiversity and the health of our planet.
