Light penetrates the uppermost of these, the littoral, which contains floating and rooted plants. The other zones also each play unique roles in the ecosystem.Some of the important abiotic environmental factors of aquatic ecosystems include substrate type, water depth, nutrient levels, temperature, salinity, and flow.
