Zoology - Organisms and Populations Question with Solution | TestHub

Graph I depicts conformers, Graph II depicts regulators, Graph III depicts partial regulators

Salamandra (Salamander)- an amphibian, Trygon (Sting ray) - a cartilaginous fish, Hippocampus (seahorse) - a bony fish, Myxine (hag fish) - a cyclostome, Balanoglossus - a hemichordate, Amphioxus - a cephalochordate can't regulate their body temperature. Their internal temperature changes with the surrounding, so they are Conformers. Corvus (crow), Struthio (ostrich), Psittacula (parrot) are all birds and can regulate their internal body temperature. Hence they are regulators. Canis (dog) is a mammal which is a regulator too. Spermophilus tridecemlineatus (ground squirrel) and Sorex araneus (shrews) are mammals which are partial regulators. At low temperatures their internal temperature rises with the external temperature but as the temperature increases they maintain a constant internal temperatures
