Different species flourish within different ranges of pH with the optima for most aquatic organisms falling between pH 6.5-8. So, how is homeostasis maintained? . Furthermore, homeostasis is a self-regulating process that regulates internal variables necessary to sustain life. This causes the release of even more oxytocin and produces even stronger contractions. Ask curriculum-related questions and receive answers from qualified teachers. Booker Taliaferro Washington was an American educator, author, and adviser to multiple presidents of the United States. Answer (1 of 25): It is necessary to maintain optimal conditions for metabolism to progress properly. The change in blood pH causes muscle twitches and fatigue. Why do we need to maintain a constant homeostasis? Untreated, the condition becomes dangerous to the individual. Homeostasis is the ability to maintain a relatively stable internal environment that persists despite external changes. 1. . Living organisms from plants to puppies; need to maintain homeostasis constantly to properly grow, work, and survive. A familiar example of homeostatic regulation in a mechanical system is the action of a room-temperature regulator, or thermostat. The pH scale runs from 0 - 14, with acidic solutions having a pH from 0 - 6, neutral solutions having a pH of 7, and basic solutions having a pH from 8-14. .
