exogeneous

Exogenous refers to a condition or process that originates from outside a system or environment. The term is often used in contrast to endogenous, which describes internal or self-generated processes. In scientific and technical contexts, exogenous variables are external factors that influence a system, such as economic models where exogenous variables are factors outside the economy that affect it, like government policies or global events. In biological contexts, exogenous factors might include environmental conditions or external stimuli that affect an organism's behavior or development. The concept of exogenous factors is crucial in various fields, including economics, biology, and engineering, as it helps in understanding how external influences impact internal systems and processes.
