Marine science studies the interactions between the living world and its environment. It is a multi-disciplinary field, combining aspects of many disciplines, such as biology, geography, ecological economics, chemistry, environmental history, and sociology.
Marine ecology is the study of living things in the ocean and how they interact with their environment. It is an interdisciplinary science that combines biology with physical sciences (e.g. geology, chemistry, oceanography, geophysics, statistics).
The aquatic environment can be defined as interacting system of resources such as water and biota. The world has a variety of lotic and lentic aquatic environments, which are a major source of food to millions of people across the earth. Hence, the dynamics of aquatic environment depends on the properties of water.
