How do abiotic factors affect biotic factors in an aquatic ecosystem?
Abiotic factors are parts of an environment that are not alive, but that affect the ecosystem. Factors that affect aquatic ecosystems include water flow rate, salinity, acidity, oxygen, light levels, depth, and temperature. Light levels affect photosynthesizing plants and predation.
