Feb 5, 2013 · 1. As the others have said, animals and insects (and even plants) generate heat through metabolism and can regulate their temperature this way. Just wanted to add a third point that mammals have developed brown fat, fat tissue which is dark with extra mitochondria which burn energy to generate heat. These are rich with uncoupling protein (a ...
Oct 31, 2023 · Convection currents of air remove heat from the surface of dry skin as the air passes over it. Heat can be conducted from one surface to another during direct contact with the surfaces, such as an animal resting on a warm rock. Figure 33.13.1 33.13. 1: Mechanisms for heat exchange: Heat can be exchanged by four mechanisms: (a) radiation, (b ...
Mar 5, 2024 · The temperature of cold blooded or ectothermic animals varies with the environment, while warm blooded or endothermic animals maintain a relatively stable temperature. The animal kingdom falls into two categories based on how species regulate their body temperature: ectothermic and endothermic. This distinction plays a crucial role in how ...
amphibian. invertebrate. ectotherm, any so-called cold-blooded animal —that is, any animal whose regulation of body temperature depends on external sources, such as sunlight or a heated rock surface. The ectotherms include the fishes, amphibians, reptiles, and invertebrates. The body temperature of an aquatic ectotherm is usually very close ...

Jan 18, 2024 · Endotherms, or “warm-blooded” animals, accomplish this by creating their own body heat, while ectotherms get their body heat from sources like the sun. Ectotherms will commonly bask in the sun ...
Cannon (1932) described the capacity for an animal to regulate its internal environment as the product of a suite of physiological processes, called homeostasis. Homeostatic mechanisms are dynamic ...

An ectotherm (from the Greek ἐκτός (ektós) "outside" and θερμός (thermós) "heat"), more commonly referred to as a " cold-blooded animal ", [1] is an animal in which internal physiological sources of heat, such as blood, are of relatively small or of quite negligible importance in controlling body temperature.
