(a) ‘‘Organisms may be conformers or regulators.’’ Explain this statement and give one example of each.
(b) Why are there more conformers than regulators in the animal world ?
(a) Conformers - Organisms which cannot maintain a constant internal environment undercharging external environmental conditions, change body temperature and osmotic concentration with a change in the external environment. Eg - fishes, etc.
Regulators - Organisms which can maintain homeostasis, maintain constant body temperature and osmotic concentration. Eg- mammals.
(b) Thermoregulation is energetically expensive for animals.
