Difference Between An Animal That Is A Regulator And One That Is A Conformer

Homeostasis is a tendency of a living body to acquire a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. It is a self-regulating process by which biological systems tend to maintain stability while adjusting to conditions that are optimal for survival. With the help of homeostasis, animals can regulate their internal temperature to maintain a constant, stable condition. The stability attained by homeostasis is actually a state of dynamic equilibrium, in which continuous change occurs yet relatively uniform conditions prevail. There are two ways in which living entities can achieve the equilibrium in their internal environment- By conforming their internal temperature to the external temperature. Or, by regulating their internal temperature.

Thus, based on how the organisms behave to the changes in their surroundings, they are classified as-

Ans. Both regulators and conformers get affected by climatic changes. Temperature variations affect their longevity and aging. It is found that animals living in cool climates live longer. And an increase in temperature over time affects the lifespans of animals. This is because, at low temperatures, enzymes become inhibited, but in high temperatures, respiratory and circulatory systems struggle to meet oxygen demand. This negatively affects protein structure and function, membrane fluidity, and gene expression. Thus, resulting in accelerated biochemical pathways resulting in a higher rate of metabolism. All of these make the animals more prone to diseases. On the other hand, in colder climates, the neuroendocrine processes resulting from low temperatures are correlated to slower aging and longer life span. Therefore, animals, be it regulators or conformers, face challenges with regard to climate change.

They show homeostasis to some extent.

They show comparatively lesser homeostasis.

They are capable of generating internal heat.

They are not capable of generating internal heat.

Due to internal heat generation, they can regulate their body temperature.

They must change their body temperature according to their surroundings

They are also called endotherms or warm-blooded animals.

They are also called ectotherms or cold-blooded animals.

Organisms in this group are more active.

Organisms in this group are less active.

They are widely distributed in the ecosystem.

Their distribution is narrow as compared to regulators.

They have a fixed osmotic concentration in the body fluids.

The osmotic concentration of body fluids of these animals fluctuates depending on the external medium.

More energy is expended to maintain constancy

Less amount of energy is expended in order to maintain constancy

Examples- Reptiles, insects, amphibians, fishes, etc.
