Abiotic component. 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 ...
The transition from non-life to life has never been observed experimentally, but many proposals have been made for different stages of the process. The study of abiogenesis aims to determine how pre-life chemical reactions gave rise to life under conditions strikingly different from those on Earth today.
Abiotic stress. Abiotic stress is the negative impact of non-living factors on the living organisms in a specific environment. [1] The non-living variable must influence the environment beyond its normal range of variation to adversely affect the population performance or individual physiology of the organism in a significant way.

Ecosystem ecology is the integrated study of living (biotic) and non-living (abiotic) components of ecosystems and their interactions within an ecosystem framework. This science examines how ecosystems work and relates this to their components such as chemicals, bedrock, soil, plants, and animals. Ecosystem ecology examines physical and ...
An ecosystem (or ecological system) consists of all the organisms and the abiotic pools (or physical environment) with which they interact. [3][4]: 5 [2]: 458 The biotic and abiotic componentsare linked together through nutrient cycles and energy flows. [5] "Ecosystem processes" are the transfers of energy and materials from one pool to another ...

The balance of nature (referred to as "the circle of life") is a major theme of the 1994 film, The Lion King. In one scene, the character Mufasa describes to his son Simba how everything exists in a state of delicate balance. [1][9] The character Agent Smith, in the 1999 film The Matrix, describes humanity as a virus, claiming that humans fail ...
In ecology, edge effects are changes in population or community structures that occur at the boundary of two or more habitats. [ 1 ] Areas with small habitat fragments exhibit especially pronounced edge effects that may extend throughout the range. As the edge effects increase, the boundary habitat allows for greater biodiversity.
