Question

Compare the behavior of an endotherm and an ectotherm on a hot summer day. How does each organism respond to changes in the environment?

Answer 1

sample response: Endotherms are able to maintain a constant body temperature. An endotherm may respond to a hot summer day by sweating or panting. The body temperature of an ectotherm, on the other hand, changes with its surroundings. In order to stay cool, an ectotherm must move somewhere cooler like the shade of a plant or rock or seek cool water to lay in

Step-by-step explanation:

Answer 2

Endotherms generate most of the heat they need internally. When it's hot outside, they decrease metabolic heat production to keep their body temperature constant. Because of this, the internal body temperature of an endotherm is more or less independent of the temperature of the environment.
Contrarily, Ectotherms' body temperature primarily depends on external heat sources. That is, ectotherm body temperature rises and falls along with the temperature of the surrounding environment. So if it is hot outside their body temperature rises as well.
