Ocean Ecosystem

An ocean ecosystem encompasses the diverse communities of plants, animals, and microorganisms living in ocean waters. It includes various habitats like coral reefs, open seas, and deep-sea environments. Key components are phytoplankton, which produce oxygen and serve as the base of the food web, fish, marine mammals, and seabirds. These ecosystems are vital for regulating the Earth's climate, providing food, and supporting global biodiversity. However, they face threats from pollution, overfishing, and climate change, which disrupt the balance and health of ocean life, impacting both marine species and human communities reliant on the ocean.
