[QUOTE="ufs, post: 4499529, member: 487634"] [h2]Homework Statement [/h2] "1. The net change, C, in the energy level of a forging animal over a period of time [I]t[I][/I][/I] is equal to the energy intake, [I]I[I][/I][/I], minus the energy expended, E: C= I-E Suppose that the energy intake (per unit time, j>0, is a constant. Then, over a time interval [I]t[I][/I][/I], the total energy intake is I=jt. Further, suppose that B is the basal metabolic rate, and f is the energy required for foraging activity per unit time t, (where B, f>0 are constants). Then the total energy required to forage for time t is E= ft+B. a) Determine the time at which energy intake I balances energy spent, E i.e the time at which the net change in the energy level is zero. b) What conditions must be satisfied by the constants f and j (other than f,j>0) defined above for your answer to be biologically meaningful? c)Explain your answer in (b): what is this saying about the foraging? [h2]Homework Equations[/h2] [h2]The Attempt at a Solution[/h2] a) C= I-E 0=I-E 0=(jt)-E E/j=t b) I am not sure what it wants but this is what I did randomly. E-B/t=f and I/t=j c) Not sure on what to say due to (b) [/QUOTE]
