Ecology (from Ancient Greek οἶκος (oîkos) ' house ' and -λογία ' study of ') is the natural science of the relationships among living organisms and their environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere levels.
Ecosystem ecology is the "study of the interactions between organisms and their environment as an integrated system". [ 2 ] : 458 The size of ecosystems can range up to ten orders of magnitude , from the surface layers of rocks to the surface of the planet.
Ecology and Evolutionary biology in North America is based on research impact determined by the top 10% of ecology programs. The interactive web of organisms and environment are all part of what the field of Ecology explores. There have been studies in evolution that have worked to prove that "modern organisms have developed from ancestral ones."
Biology is the scientific ... every cell in the organism's body is derived ultimately ... thereby increasing the match between the organisms and their environment. ...
These factors may include descriptions of the organism's life history, habitat, trophic position (place in the food chain), and geographic range. According to the competitive exclusion principle, no two species can occupy the same niche in the same environment for a long time.
Habitat can be defined as the natural environment of an organism, the type of place in which it is natural for it to live and grow. [4] [5] It is similar in meaning to a biotope; an area of uniform environmental conditions associated with a particular community of plants and animals. [6]
An evolved organism takes its form by the partially understood mechanisms of evolutionary developmental biology, in which the genome directs an elaborated series of interactions to produce successively more elaborate structures. The existence of chimaeras and hybrids demonstrates that these mechanisms are "intelligently" robust in the face of ...
Ecology – scientific study of the distribution and abundance of living organisms and how the distribution and abundance are affected by interactions between the organisms and their environment. The environment of an organism includes both physical properties, which can be described as the sum of local abiotic factors such as solar insolation ...
