Question

Give an example for:
A) An endothermic animal
B) An endothermic animal
C) An organism of benthic zone

Answer 1

Hint: (a) Endothermic animals are those animals that maintain constant blood heat.
(b) Ectothermic animals are those animals during which the regulations of the blood heat depends on the external environment.
(c) Benthic zone is the deepest zone of the ocean.

Complete answer:
(a) Endothermic animals: Birds like crows, sparrows, pigeons, cranes, etc. and mammals like bears, cows, rats, rabbits, etc. are endothermic animals.
(b) Ectothermic animals: Fishes like sharks, amphibians like frogs, and reptiles like tortoises, snakes, and lizards are ectothermic animals.
(c) Organism of benthic zone: Decomposing bacteria is an example of an organism found within the benthic zone of a water body.
Key point:
Most animals got to maintain their core blood heat within a comparatively narrow range.
Endotherms use internally generated heat to take care of blood heat . Their blood heat tends to remain steady no matter the environment.
Ectotherms depend mainly on external heat sources, and their blood heat changes with the temperature of the environment.
Animals exchange heat with their environment through radiation, conduction—sometimes aided by convection—and evaporation.

Note:
For both endotherms and ectotherms, blood heat depends on the balance between heat generated by the organism and warmth exchanged with—lost to or gained from—the environment. Heat always moves from warmer to cooler objects, as described within the Second Law ofThermodynamics.
There are three main ways in which an organism can exchange heat with its environment: radiation, conduction—along with convection—and evaporation.
