    Environmental gradients can be related to factors such as altitude, depth, temperature, soil humidity and precipitation. Often times, a multitude of biotic (living) factors are closely related to these gradients; as a result of a change in an environmental gradient, factors such as species abundance , population density, morphology , primary ...

    The influences that biotic factors have on the way landforms are developed. [ 3 ] There has been much work on these approaches such as; the effect that parent material has on the distribution of plants, [ 3 ] the increase of precipitation due to an influx of transpiration , the stability of a hillslope due to the abundance of vegetation or, the ...

  8. Lake ecosystem - Wikipedia

    en.wikipedia.org/wiki/Lake_ecosystem

    Light, water depth, and substrate types are the most important factors controlling the distribution of submerged aquatic plants. [10] Macrophytes are sources of food, oxygen, and habitat structure in the benthic zone, but cannot penetrate the depths of the euphotic zone, and hence are not found there.

  9. Ecosystem ecology - Wikipedia

    Ecosystem services are ecologically mediated functional processes essential to sustaining healthy human societies. [6] Water provision and filtration, production of biomass in forestry, agriculture, and fisheries, and removal of greenhouse gases such as carbon dioxide (CO 2) from the atmosphere are examples of ecosystem services essential to public health and economic opportunity.
