Detailed explanation-1: -What factors affect life in aquatic ecosystems? Aquatic organisms are affected primarily by the water’s depth, temperature, flow, and amount of dissolved nutrients. Water depth strongly influences aquatic life because sunlight penetrates only a relatively short distance through water.

Detailed explanation-2: -Some of the important abiotic environmental factors of aquatic ecosystems include substrate type, water depth, nutrient levels, temperature, salinity, and flow. It is often difficult to determine the relative importance of these factors without rather large experiments.

Detailed explanation-3: -Whether freshwater or saltwater, aquatic environments are highly influenced by levels of sunlight, temperature, water depth, and the chemical composition of the water. These factors not only influence the potential biodiversity, or variety of species, but also where these species are able to live and survive.

Detailed explanation-4: -Abiotic factors that influence aquatic biomes include light availability, depth, stratification, temperature, currents, and tides.
