A diorama is a replica of a scene, typically a three-dimensional model either full-sized or miniature. Sometimes it is enclosed in ...
River ecosystems are prime examples of lotic ecosystems. Lotic refers to flowing water, from the Latin lotus, meaning washed. Lotic waters range from springs only a few centimeters wide to major rivers kilometers in width. [5] Much of this article applies to lotic ecosystems in general, including related lotic systems such as streams and springs.
As the summer begins, two distinct layers become established, with such a large temperature difference between them that they remain stratified. The lowest zone in the lake is the coldest and is called the hypolimnion. The upper warm zone is called the epilimnion. Between these zones is a band of rapid temperature change called the thermocline ...
External factors, also called state factors, control the overall structure of an ecosystem and the way things work within it, but are not themselves influenced by the ecosystem. On broad geographic scales, climate is the factor that "most strongly determines ecosystem processes and structure".
Ecosystems may be habitats within biomes that form an integrated whole and a dynamically responsive system having both physical and biological complexes. Ecosystem ecology is the science of determining the fluxes of materials (e.g. carbon, phosphorus) between different pools (e.g., tree biomass, soil organic material).
The relationship between ecosystem complexity and stability is a major topic of interest in ecology.Use of ecological networks makes it possible to analyze the effects of the network properties described above on the stability of an ecosystem.
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.
These homemade ecosystems (which also include closed terrariums) are often made by hobbyists in what are often jars (hence the name jarrarium) or sealed glass tanks with the intention of mimicking a larger ecosystem. They are often made by going out and collecting material (including soil, plants, small insects and water if an aquatic ecosystem ...
