The ocean is home to a diverse range of life forms, from tiny plankton to massive whales. It supports various ecosystems, including coral reefs, deep-sea habitats, and open ocean environments. Many species, such as sea turtles, dolphins, and sharks, play crucial roles in maintaining the balance of these ecosystems. Marine life relies on the ocean's resources for food, shelter, and reproduction. Plants like kelp and phytoplankton produce oxygen and serve as the foundation of the food web. Additionally, the ocean's currents and temperatures influence the distribution and behavior of marine species, making it a dynamic and interconnected environment.
