Marine Ecology is the study of the relationships between marine organisms and their environment. It encompasses various ecosystems, including coral reefs, mangroves, and open oceans, focusing on how species interact with each other and their habitats. Understanding these interactions is crucial for conservation efforts and managing marine resources sustainably. This field also examines the impact of human activities, such as pollution and overfishing, on marine life. By studying these dynamics, scientists aim to protect biodiversity and ensure the health of our oceans, which are vital for the planet's overall well-being.
