Natural resources may be further classified in different ways. [1] Resources can be categorized based on origin: Abiotic resources comprise non-living things (e.g., land, water, air, and minerals such as gold, iron, copper, silver). Biotic resources are obtained from the biosphere.
Biotic materials in soil include humic substances such as humic acids, fulvic acids and humin. Some biotic material may not be considered to be organic matter if it is low in organic compounds , such as a clam 's shell, which is an essential component of the exoskeleton of bivalve mollusks made of calcium carbonate ( CaCO 3 ), but contains ...
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 can be consumed by one organism and, as a result, become unavailable to another organism.
Natural resources can be a substantial part of a country's wealth; [7] however, a sudden inflow of money caused by a resource extraction boom can create social problems including inflation harming other industries ("Dutch disease") and corruption, leading to inequality and underdevelopment, this is known as the "resource curse".
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; Biotic community, all the interacting organisms living together in a specific habitat
Abiotic components include physical conditions and non-living resources that affect living organisms in terms of growth, maintenance, and reproduction. Resources are distinguished as substances or objects in the environment required by one organism and consumed or otherwise made unavailable for use by other organisms.
Eugene Odum, one of the founders of the science of ecology, stated: "Any unit that includes all of the organisms (i.e.: the "community") in a given area interacting with the physical environment so that a flow of energy leads to clearly defined trophic structure, biotic diversity, and material cycles (i.e.: exchange of materials between living ...
