Is a river abiotic or abiotic factor?

River ecosystems are flowing waters that drain the landscape, and include the biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions of its many parts.

What abiotic factors might affect a river 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.

What are 5 examples of abiotic factors?

Common examples of abiotic factors include:

  • Wind.
  • Rain.
  • Humidity.
  • Latitude.
  • Temperature.
  • Elevation.
  • Soil composition.
  • Salinity (the concentration of salt in water)

Is a lake an abiotic factor?

Abiotic Factors of Lakes

Most lakes are freshwater, although there are some examples of lakes with high salinity, like the Caspian Sea in Europe. The important abiotic factors in lakes are the low salinity, temperature, sunlight, and soil composition. Temperature varies in the lake depending on depth and season.

What are some biotic factors in a river?

For example in the river a biotic factor can be small frogs, plants, fish anything living in the river. In the sea the biotic factors are any large fish or sea creatures living in that area, also any small organisms like shrimp and other things you can see.
