Summary Introduction

An ecosystem that exists in water is called as aquatic system. The two types of aquatic ecosystem are freshwater ecosystem and marine ecosystem. The main primary producer in the freshwater aquatic ecosystem consists of phototrophic microorganisms. Most of the produced organic matter is consumed by the bacteria. It will lead to oxygen depletion in the environment. The Biological Oxygen Demand (BOD) of the water body specifies its relative content of organic matter that can be oxidized biologically.
