Resource (biology) In biology and ecology, a resource is a substance or object in the environment required by an organism for normal growth, maintenance, and reproduction. Resources box can be consumed by one organism and, as a result, become unavailable to another organism. [1] [2] [3] For plants key resources are light, nutrients, water, and ...
In ecology, the competitive exclusion principle, [1] sometimes referred to as Gause's law, [2] is a proposition that two species which compete for the same limited resource cannot coexist at constant population values. When one species has even the slightest advantage over another, the one with the advantage will dominate in the long term.
In biology and ecology, abiotic components or abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. Abiotic factors and the phenomena associated with them underpin biology as a whole. They affect a plethora of species, in all forms of environmental ...
Realized niche width is a phrase relating to ecology, is defined by the actual space that an organism inhabits and the resources it can access as a result of limiting pressures from other species (e.g. superior competitors). An organism's ecological niche is determined by the biotic and abiotic factors that make up that specific ecosystem that ...
In ecology, primary production is the synthesis of organic compounds from atmospheric or aqueous carbon dioxide. It principally occurs through the process of photosynthesis , which uses light as its source of energy, but it also occurs through chemosynthesis , which uses the oxidation or reduction of inorganic chemical compounds as its source ...
Florida is surrounded on three sides by bodies of water: the Gulf of Mexico to the west, Florida Bay to the south, and the Atlantic Ocean to the east. In addition to its coastal habitats, Florida has many varied wetland habitats, such as marshland, swampland, lakes, springs, and rivers. Florida's largest river is the St. Johns River.
Soil ecology is the study of the interactions among soil organisms, and between biotic and abiotic aspects of the soil environment. [1] It is particularly concerned with the cycling of nutrients, formation and stabilization of the pore structure, the spread and vitality of pathogens, and the biodiversity of this rich biological community .
English ecologist Charles Elton applied the term resistance to the ecosystem properties which limit the ability of introduced species to successfully invade communities. These properties include both abiotic factors like temperature and drought, and biotic factors including competition, parasitism, predation and the lack of necessary mutualists.
