homeostasis
Quick Summary
Homeostasis refers to the ability of biological systems to maintain stability and adjust to conditions optimal for survival. This self-regulating process, often involving feedback control, ensures a dynamic equilibrium where internal conditions remain relatively constant despite external changes. For example, the human body regulates its temperature through complex mechanisms involving the brain, nervous system, and circulatory system.1
In ecology, homeostasis applies to ecosystems, where biodiversity and interactions between species contribute to stability. This concept, also known as ecological resilience, describes an ecosystem's ability to maintain its structure and function after disturbances. A diverse ecosystem is generally more resilient and recovers faster from damage. Habitat loss, fragmentation, and degradation are major threats to ecological homeostasis, leading to biodiversity loss. Trophic cascades, where the removal or addition of top predators impacts populations throughout the food chain, also demonstrate how ecosystems maintain balance.2345
