environment (redirected from extracellular environment)

environment

A particular configuration of hardware or software. "The environment" refers to a hardware platform and the operating system that is used in it. A programming environment would include the compiler and associated development tools.

Environment is used in other ways to express a type of configuration, such as a networking environment, database environment, transaction processing environment, batch environment, interactive environment and so on. See platform.

Environment

The sum of all external factors, both biotic (living) and abiotic (nonliving), to which an organism is exposed. Biotic factors include influences by members of the same and other species on the development and survival of the individual. Primary abiotic factors are light, temperature, water, atmospheric gases, and ionizing radiation, influencing the form and function of the individual.

For each environmental factor, an organism has a tolerance range, in which it is able to survive. The intercept of these ranges constitutes the ecological niche of the organism. Different individuals or species have different tolerance ranges for particular environmental factors—this variation represents the adaptation of the organism to its environment. The ability of an organism to modify its tolerance of certain environmental factors in response to a change in them represents the plasticity of that organism. Alterations in environmental tolerance are termed acclimation. Exposure to environmental conditions at the limit of an individual's tolerance range represents environmental stress.
