Why is homeostasis particularly important for organisms in variable environments?
Why is homeostasis particularly important for organisms in variable environments?
- It facilitates faster reproduction rates under stress.
- It decreases the need for energy consumption.
- It enables them to adapt and survive despite external changes. (correct)
- It allows them to exhibit superior mobility and agility.

Study Notes
Definition of Homeostasis
- Introduced by Walter B. Cannon, emphasizing self-regulating biological processes.
- Essential for maintaining stability amid changing environmental conditions.
Importance of Homeostasis
- Critical for the continuity of life, ensuring stable body functions.
- Helps organisms adapt to various terrestrial and aquatic environments.
Environmental Influence
- Organisms are subject to variable conditions, leading to physical and physiological changes.
- These environmental factors can range from moderate to extreme, impacting the internal state of organisms.
Internal Body Environment
- Comprises body fluids, tissues, organs, and systems, requiring regulation within suitable limits.
- Components are physiologically integrated and coordinated to function efficiently.
Regulatory Systems
- Endocrine and nervous systems are pivotal in homeostatic regulation.
- Responsible for various functions such as osmoregulation (water balance), excretion (waste removal), and thermoregulation (temperature control).
Homeostatic Processes
- Regulatory functions work to maintain a balance between external and internal environments.
- Ensures the organism's adaptability and overall well-being in response to environmental changes.
