Answer #1

Solution :

The population size of two competing species changes is explained and calculated by Lotka Volterra model.

The formula for calculation when two species are competing with each other is as follows

dN1/dt=r1N1(K1-N1-\alphaN2/K1)

dN2/dt= r2N2(K2-N2-\betaN1/K2)

\alpha is the effect of species 2 on the growth of species 1

\beta is the effect of species 1 on the growth of species 2.
