Homeotherm

Homeotherm is an organism that maintains its body temperature at a constant level, usually above the temperature of its surroundings, by its metabolic activity. This is in contrast to poikilotherm organisms, which do not have constant body temperatures.

Overview[edit | edit source]

Homeotherms, also known as endotherms, are capable of internal generation of heat to maintain body temperature. This is achieved through a variety of physiological and behavioral adaptations, including insulation, fat storage, and metabolic heat production. Homeotherms include mammals and birds, and to a lesser extent, certain fish and insects.

Characteristics[edit | edit source]

Homeotherms have a number of characteristics that distinguish them from other organisms. These include:

High metabolic rate: Homeotherms have a high metabolic rate, which allows them to generate heat internally. This is in contrast to ectotherms, which rely on external sources of heat.

Thermoregulation: Homeotherms are capable of maintaining a stable internal body temperature regardless of external conditions. This is achieved through a combination of behavioral, physiological, and biochemical mechanisms.

Insulation: Homeotherms have various forms of insulation, such as fur, feathers, and fat, which help to retain body heat.

Advantages and Disadvantages[edit | edit source]

Homeothermy has several advantages, including the ability to remain active in a wide range of environmental conditions, and the capacity for high levels of sustained activity. However, it also has disadvantages, such as the need for a constant supply of food to fuel the high metabolic rate, and the risk of overheating.
