The biotic potential is the quantitative expression of the ability of a species to face natural selection in any environment. The main equilibrium of a particular population is described by the equation: Chapman also relates to a "vital index", regarding a ratio to find the rate of surviving members of a species, whereas; Vital Index = (number ...
In ecology, a biological interaction is the effect that a pair of organisms living together in a community have on each other. They can be either of the same species (intraspecific interactions), or of different species (interspecific interactions). These effects may be short-term, or long-term, both often strongly influence the adaptation and ...
Ecosystem classifications are specific kinds of ecological classifications that consider all four elements of the definition of ecosystems: a biotic component, an abiotic complex, the interactions between and within them, and the physical space they occupy. Biotic factors of the ecosystem are living things; such as plants, animals, and bacteria ...
Natural-resource meaning [:] An actual or potential form of wealth supplied by nature, as coal, oil, water power, timber, arable land, etc. A material source of wealth, such as timber, fresh water, or a mineral deposit, that occurs in a natural state and has economic value. Something, such as a forest, a mineral deposit, or fresh water, that is ...
Biotics describe living or once living components of a community; for example organisms, such as animals and plants. Biotic may refer to: Life, the condition of living organisms. Biology, the study of life. Biotic material, which is derived from living organisms. Biotic components in ecology. Biotic potential, an organism's reproductive capacity.
Forest ecology is the scientific study of the interrelated patterns, processes, flora, fauna and ecosystems in forests. [1] The management of forests is known as forestry, silviculture, and forest management. A forest ecosystem is a natural woodland unit consisting of all plants, animals, and micro-organisms ( Biotic components) in that area ...
This definition is based on that of “biome,” the biotic and abiotic factors of given environments. Others in the field limit the definition of microbiome to the collection of genes and genomes of members of a microbiota. It is argued that this is the definition of metagenome, which combined with the environment constitutes the microbiome.
These two gradients taken together can be expressed as an electrochemical gradient, providing energy for abiogenic synthesis. The proton motive force can be described as the measure of the potential energy stored as a combination of proton and voltage gradients across a membrane (differences in proton concentration and electrical potential).
