A functional group is a collection of organisms that share characteristics within a community. Ideally, these would perform equivalent tasks based on domain forces, rather than a common ancestor or evolutionary relationship.
The map shows the EFTs of the 2001–2008 period. Ecosystem Functional Type (EFT) is an ecological concept to characterize ecosystem functioning. Ecosystem Functional Types are defined as groups of ecosystems or patches of the land surface that share similar dynamics of matter and energy exchanges between the biota and the physical environment.
Functional groups of cells Organ: Functional groups of tissues Organ system: Functional groups of organs Ecological levels: Organism: The basic living system, a functional grouping of the lower-level components, including at least one cell Population: Groups of organisms of the same species: Guild: Interspecific groups of organisms carrying the ...
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]
The reactivity of a functional group can be modified by other functional groups nearby. Functional group interconversion can be used in retrosynthetic analysis to plan organic synthesis. A functional group is a group of atoms in a molecule with distinctive chemical properties, regardless of the other atoms in the molecule. The atoms in a ...
A functional characteristic is known in evolutionary biology as an adaptation, and the research strategy for investigating whether a character is adaptive is known as adaptationism. Although assuming that a character is functional may be helpful in research, some characteristics of organisms are non-functional, formed as accidental spandrels ...
WASHINGTON (Reuters) -President-elect Donald Trump said on Saturday the U.S. should not be involved in the conflict in Syria, where rebel forces are threatening the government of President Bashar ...
Trophic species are functional groups that have the same predators and prey in a food web. Common examples of an aggregated node in a food web might include parasites , microbes, decomposers , saprotrophs , consumers , or predators , each containing many species in a web that can otherwise be connected to other trophic species.
