Question $3$

For your summer project, you decide to test the form of interaction that occurs between three coexisting fish species $($A$,$ B$,$ C$,$ and D$),$ all of which are territorial. Each of the species reproduces continually, reaches maturity in less than $12$ months, and lives for roughly $4$ years. The diagram below on the left shows an area of habitat with square territory sites, each of which is occupied. You plan to remove all of the resident fishes. After $24$ months, you plan to record the fish species that have re$-$colonized each territory site. On the diagram, indicate how you expect the territories would be recolonized if the four species are partitioning resources according to the competitive resource partitioning hypothesis. Please explain your answer
