homeostasis. Homeostasis refers to the mechanisms and processes that organisms use to maintain stable internal conditions despite changes in their external environment. These responses help ensure that vital conditions, such as temperature, pH levels, fluid balance, and nutrient levels, remain within a range that is conducive to survival and proper functioning.
For example:
- Growth can be influenced by environmental factors such as light, water, and nutrients.
- Migration in animals often occurs in response to seasonal changes, such as temperature fluctuations or food availability.
- Movement toward or away from stimuli (like light or predators) helps organisms adapt to their surroundings.
- Hibernation allows certain animals to conserve energy during periods of cold temperatures and food scarcity.
Collectively, these responses help living organisms adjust to their environments and sustain life.
