SSC MTS EXAM

Detailed explanation-1: -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.

Detailed explanation-2: -Cold-blooded animals cannot generate their own body heat, but they do regulate it by changing their environment. Alligators and other reptiles often lie in the sun to warm themselves. On the other hand, they cool off by taking a dip in the water, moving into the sade of a rock or crawling into a burrow in the ground.

Detailed explanation-3: -Their body temperature tends to stay steady regardless of environment. Ectotherms depend mainly on external heat sources, and their body temperature changes with the temperature of the environment. Animals exchange heat with their environment through radiation, conduction-sometimes aided by convection-and evaporation.

Detailed explanation-4: -Ectotherm/Ectothermic. A cold-blooded animal; that is, an animal whose body temperature varies with the temperature of its surroundings. Ectotherms cannot produce their own body heat./To be an ectotherm.
