Q27 - Thermal Metabolic Profiles of Five Animal Species
Figure Q.27 shows the changes in metabolic rates of adult individuals of five animal species in response to temperature changes of the external environment (EM). The individual body weights of the five species were similar (about 30 grams). The data were measured from the animals when they were staying at rest.
Figure 1.
Using the information and data, determine which of the statements are true or which are false.
A. Species IV was an ectothermic animal.
B. Species II had the highest thermo-insulating ability among the five species.
C. Species III possessed the highest basal metabolic rate among the five species.
D. Increase in body temperature in species V was mainly dependent on metabolism.
