Aquatic ecosystem can be broadly classified into Marine Ecosystem and Freshwater Ecosystem. 5 points christian24611 Asked 09.12.2018. Ecologists tend to think of these systems as identifiable at many different scales with boundaries selected to highlight internal and external interactions. Aquatic organisms are affected primarily by the water's depth, temperatures, flow, and amount of dissolved nutrients What are the major categories of freshwater ecosystems? The sources of organic matter in these systems can be both internal (autochthonous) and external (allochthonous). For many ecologists, boundaries are human constructs: lines on a map drawn by a scientist that may or may not correspond with any obvious physical discontinuities in nature. C.

Only the organisms that are able to survive in the conditions of a particular habitat and use the resources available there will thrive. Ecology is the scientific study of how organisms interact with each other and with their environment. The nature and characteristics of the communities of living or biotic organisms and non-living or abiotic factors which interact with and interrelate to one another are determined by the aquatic surroundings of their environment they are dependent upon. Aquatic ecosystems are fascinating, complex, and filled with interconnected parts.
