Description:Two populations that grow from the same unlimited source increase exponentially. But, even though there are no negative interactions, one of them will become increasingly dominant. Examples: 

Variables:E = Energy sourceQ, Q2 = two populations K1, K2 = growth rates K3, K4 = mortality rates Equations:DQ1 = K1*E*Q  K3*QDQ2 = K2*E*Q2  K4*Q2 Simulation:The graph shows the growth of the populations Q (green) and Q2 (blue).Source code: Compete.java
