A small lake is capable of supporting both bluegill and small-mouth bass. These two bony fish species compete for similar food resources. The carrying capacities of this lake for bluegill (K1) is 1,500 and for small-mouth bass (K2) is 500. After some careful measurement, we find that α (or α12)is 0.5 and that β (or α21) is 0.25. We stock the lake with 250 bluegill and 750 bass. Over time, will both species coexist? If so, approximately how many of each species will be present? If not, which one will be driven to extinction in this lake?

1) What is the numerical value of ‘A’?

2) What is the numerical value of ‘B’?

3) What is the numerical value of ‘C’?

4) What is the numerical value of ‘D’?

5) What is the value of N1 at the intersection of the ZNGIs?

6) What is the values of N2 at the intersection of the ZNGIs?
