MULTIPLE CHOICE,ASSURED EXCELLENCE
All questions fully answered. Answer all five questions (total of
50 marks) Question 1 [10] Explain briefly in your own words
how measuring CO2 production can be used to estimate the
metabolic rate of animals. Discuss at least two approaches in
this context. Question 2 [6] Provide a short overview and
explanation of organisms that store energy in the form of
glycogen. Also briefly explain why migrating birds do not store
energy as glycogen. Question 3 [10] Use diagrams and
equations to distinguish between the three general types of
allometric relationships. Question 4 [14] The table below
provides respiration rates at various temperatures for two
different species. Species A Species B Temperature (°C) O2
consumed (ml kg-1 hr-1) O2 consumed (ml kg-1 hr-1) 23 32 32
31 32 55 4.1. Calculate the Q10 values for oxygen consumption
rates for each of the two species. Show all your calculations. (8)
4.2. Based on the Q10 values, discuss which of the two species
is likely to be threatened more by extreme heat events in its
environment. Include in your answer a clear explanation of
what the Q10 values mean and speculate on the types of
organisms that may be represented by A and B (6) Question 5
[10] Draw an acclimation graph to illustrate the thermal
tolerance range of a hypothetical species for which the
