Description:If one population depends on another one and viceversa, we speak about cooperative existence or collaboration. Both populations grow until they reach a steady state, which depends on the growth and mortality rate of both populations. Examples: 

Variables:Q1, Q2 = Populations 1 and 2R = growth factor K18 = increasing and decreasing factors Equations:R=1/(1+K1*Q1*Q2K2*Q1*Q2)DQ1=K5*R*Q1*Q2K7*Q1*Q2K3*Q1 DQ2=K6*R*Q1*Q2K8*Q1*Q2K4*Q2 Simulation:The graph shows the changes of Q1 (green) and Q2 (red) over a time period.Source code: Coop.java
