Species A and B are lizards that eat insects. The figures at right show the preferred prey size of each species for populations living on Islands 1, 2, and 3. Determine if each of the statements below is true of these species on these islands.

A. In allopatry, species A and B eat mostly the same prey
B. In sympatry, resource partitioning has occurred
C. In sympatry, species A and B diverge in prey choice
D. Competition between species A and B affects prey choice on different islands
E. Character displacement has decreased competition between species A and species B in allopatry

Two species are said to be living in sympatric association when they live in the same area and very rarely cross with each other. However, allopatric species live in two distinct geographic areas and hence do not interact with each other. In both sympatric and allopatric case, the species do not affect the habitat, food or any other biological habit as there in no competition between the two species.

Thus, except option D all other options are true.
