Discussion Questions 1. At any given time, a 4-acre field contains an average of 200 kg dry weight of mallow plants. For these
calculations, assume that the food chain shown below is isolated and that there are no other predators or
sources of food involved.
mallow plant painted lady butterfly - phoebe - fox
Assume that the dry weight of each animal is on average as indicated below:
painted lady butterfly
phoebe
49
fox
0.19
1 kg
a. Assuming that 10% of the biomass, as measured in dry weight, is transferred from one trophic level to
the next higher level, calculate how many foxes the field could support at any given time. Show your
work and include in your calculations how many phoebes and painted lady butterflies the field could
support.

like many students at university, you may be unhappy about the results you attain in exams. you may feel that even with all you are doing there must be something more -- or different-- you could be doing to get better grades. we have all at some time or other heard of that student who only studies a couple of hours for final exams and scores a's every time. we stand in awe of those who seem to breeze through without undue effort and seem to need very little in the way of studying to nail an exam. the reasons for success, in what i think are the vast majority of cases, are less esoteric than many students think: successful students consistently apply a series of productive strategies with view to attaining clearly identified learning and grade goals throughout the academic term.
