What factors determine aquatic ecosystems?

Aquatic ecosystems are primarily defined by the characteristics of the water environment, which include depth, flow, temperature, and water chemistry.

Depth plays a crucial role in determining how much light penetrates the water, which influences the types of photosynthetic organisms that can thrive. Flow is significant because it affects sediment transport and the distribution of nutrients; different organisms are adapted to specific flow conditions. Temperature is vital since it can influence the metabolic rates of aquatic organisms, their reproduction, and overall biodiversity. Lastly, the chemistry of the water, including salinity, pH, and nutrient levels, directly impacts the types and viability of life that the ecosystem can support.

These factors interact in complex ways to create diverse habitats and biological communities, making them essential determinants of aquatic ecosystems.
