The balance of nature, also known as ecological balance, is a theory that proposes that ecological systems are usually in a stable equilibrium or homeostasis, which is to say that a small change (the size of a particular population, for example) will be corrected by some negative feedback that will bring the parameter back to its original "point of balance" with the rest of the system.
These animals may become flipped over in a fight or predator attack, so the righting response is crucial for survival. To right themselves, relatively flat animals (such as beetles) heavily rely on momentum and thrust developed by moving their limbs and wings. However, the limbs of many dome-shaped tortoises are too short to be used for righting.
An overstimulated animal will have a larger flight zone, for example an excited or scared animal. [22] A Cumulative Flight Zone is formed when animals move in a herd. In this situation the lead animal's and the following animals' Points of Balance, within the cumulative flight zone, must both be crossed to entice movement. [22]
Humans are animals, despite the fact that the word animal is colloquially used as an antonym for human. [180] [181] Ecosystems do not naturally move back towards an equilibrium using negative feedback. [182] The concept of an inherent "balance of nature" has been superseded by chaos theory. [183]
