(1 point) In a certain lake it is found that the rates of change of the population sizes of each of two species (N (t), N2(t)) is proportional to the given
population size. That is
dN1
dN2
dt
dt
= k2 N2
where kj and k2 are constants.
Find the rate of change of the ratio of population sizes (1/NV2) with respect to time (
d(NIN2)
dt
). Your answer will be in terms of k1 , k2 , N, and/or N2.
A.
d(N,IN2)
= (k2 - ki ) Ni
B.
d(N IN2)
(ki-kz )
dt
=
N
C.
d(N IN2)
(K1 -k2 )
D.
d(N IN2)
dt
= (k1 - k2) N.
E. Not enough information.
F.
d(N IN2)
KIN1
KN 2
Enter the letter corresponding to the correct answer:
?
