Answer:
The correct answer is option D) "K".
Explanation:
In this example the wolf population is described by the equation "ΔN/Δt=rN(K−N)K". Even tough the variables are not defined in the question, we can conclude that the effect of the moose population will be given by a factor that has a positive effect in the wolf's population because "as moose populations increase, wolf populations also increase". The factor "K" fits the description because it gives a positive effect on "ΔN/Δt". "K" is a factor that multiplies "rN" at two different levels, therefore the higher the value of "K", the higher value of "ΔN/Δt" will be.
