4. Assume two populations are competing for a shared limiting resource. Population N, has a carrying capacity of 2000 and Population N2 has a carrying capacity of 750. The alpha value is 2 and the beta value is 0.5. If N, starts at a size of 1000 individuals, and N2 starts at a size of 400 individuals, which population will eventually outcompete the other? Attach a graph of the zero growth isoclines for both populations.
