Freshwater Ecosystems - Freshwater Ecosystems The types of organisms in an aquatic ecosystem are mainly determined by the water s salinity. It is classified into two main categories: Terrestrial ecosystems and Aquatic ecosystems. Freshwater ecosystems in streams can have areas of fast-moving and slow-moving water, with organisms adapted to each area. It includes three subclasses and 7 orders. • Classified based of dominant species/genera. The drainage basin includes the rivers and streams in which the water drains. Molecular studies have identified many abundant lake bacteria, but there is a large variation in the taxonomic or phylogenetic breadths among the methods used for this … Bailey HC, Elphick JR, Krassoi R, Lovell A (2001) Joint acute toxicity of diazinon and ammonia to Ceriodaphnia dubia. • As a result, aquatic ecosystems are divided into freshwater and marine ecosystems.
