Endotherms generate most of the
heat they need internally. When it's cold out, they increase 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.
This pattern is shown
on the graph below: the mouse maintains a steady body temperature close to 37° C across a wide range of external temperatures.
For ectotherms,
on the other hand, body temperature mainly depends on external heat sources.
That is, ectotherm body temperature rises and falls along with the temperature
of the surrounding environment. Although ectotherms do generate some metabolic
heat—like all living things—ectotherms can't increase this heat production to
maintain a specific internal temperature.
Most ectotherms do regulate their body temperature to some
degree, though. They just don't do it by producing heat. Instead, they use other strategies such as behavior like seeking sun, shade,
etc.—to find environments whose temperature meets their needs.
Isinya sudah bagis. tetapi untuk grafiknya dapat diberi deskripsi!
BalasHapusOverall, it has explained the difference between ectothermic and endothermic, but it would be even better to add images and samples of ectothermic and endothermic animals in various varieties of their habitat with a mechanism that indicates the type of animal. Is it endothermic or ectothermic?
BalasHapusya, saya sependapat dengan hisyam
BalasHapussudah baik, namun lebih baik lagi jika ditambahkan contoh hewan ectoterm maupun endoterm :) terimakasih
