Learn how exergonic metabolic reactions release heat, and how endotherms use that heat to maintain body temperature in IB Biology HL C1.1.12.
Common bottlenose dolphins, Tursiops truncatus, are marine mammals of temperate and tropical oceans throughout the world, where they feed on fish, squid and crustaceans.
Research has been carried out on a population of these dolphins in Sarasota Bay, Florida. The table shows the mean sea surface temperature in Sarasota Bay and catch per unit effort (CPUE) in winter and summer. A large CPUE indicates it would take little effort for the dolphin to catch a lot of prey.
Explain the differences in BMR between desert and polar mammals up to a mass of .
Above a body mass of 10 kg , there is little difference in BMR between desert and polar mammals.
Suggest reasons for this.
