Aquatic ecosystems consist of communities of living organisms—ranging from microorganisms to large fish and mammals—and the environment they inhabit. Relationships between different types of living organisms, and their interactions with their environment, are often complex and interdependent. Understanding these relationships and how human actions can affect them allows for better management of aquatic resources.
This section describes aquatic environments, the types of organisms that inhabit them, and the processes affecting life in these habitats:
