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.
Ecosystem respiration is the sum of respiration by all living organisms (plants, animals, and decomposers) in the ecosystem. [16] Net ecosystem production is the difference between gross primary production (GPP) and ecosystem respiration. [ 17 ]
A pyramid of energy shows how much energy is retained in the form of new biomass from each trophic level, while a pyramid of biomass shows how much biomass (the amount of living or organic matter present in an organism) is present in the organisms. There is also a pyramid of numbers representing the number of individual organisms at each ...
Community (ecology) – Associated populations of species in a given area, or Biocoenosis – Interacting organisms living together in a habitat Species – Basic unit of taxonomic classification, below genus Population – All the organisms of a given species that live in a specified region Organism – Individual living life form
Functional diversity is widely considered to be "the value and the range of those species and organismal traits that influence ecosystem functioning" [3] In this sense, the use of the term "function" may apply to individuals, populations, communities, trophic levels, or evolutionary process (i.e. considering the function of adaptations). [3]
Groups of organisms of the same species: Guild: Interspecific groups of organisms carrying the same ecological function (i.e. herbivores). Community (or biocoenosis) Guilds from all biological domains, and their interactions in a specific location. Ecosystem: Groups of organisms in conjunction with the physical environment. Biome
The science of classification, in biology the arrangement of organisms into a classification [4] "The science of classification as applied to living organisms, including the study of means of formation of species, etc." [5] "The analysis of an organism's characteristics for the purpose of classification" [6]
