B) Some physiological and anatomical explanations for the (these) principal pattern(s)
C) Evolutionary (fitness) implications of the pattern(s). That is why does the pattern exist?

Solution
The metabolic rate of various organisms found in two different geographical location was
studied with relation to the variation of temperature.The organisms choose for this study were
from different groups like some were rodents while some were mammals .Birds were also
studies
A) As shown in the graph it is vary clear that the temperature exerts effect on metabolic rate. As
the temperature increase the metabolic rate decrease and vice versa.
B) Metabolic rate also affected due to body size, the small organisms have a higher metabolic
rate as compare to larger animals.
C) Organisms of Arctic area require the much lower temperature to attain a particular metabolic
rate as compare to the tropical one which requires a higher temperature to attain the same
metabolic rate.It can be explained as that the tropical organisms has adapted at a lower
temperature while the tropical one adapted higher temperature as compare to Arctic one.After a
particular temperature, the variation in metabolic rate become negilable.After this temprature,
metabolic rate increase vary slowly and constantly with a sharp rise in temprature . Adaptation is
the main reason for such type of pattern.
D) For example, to attain 2 unit of metabolic rate jungle rat(Tropical mammal) requires
approximately 18 oC while snow bunting can survive at -10o C with same metabolic rate due to
their respective adaptation with their environment.
