Kangaroo rats are endemic to the deserts of the American southwest.In one region, two kangaroo rat species eat only seeds and arebiologically extremely similar. The two species are found inadjacent habitats. Seeds are abundant in both habitats, but lessnutritious than insects. If you were to double the amount of seedsacross both habitats and add insects as potential food, which ofthe following outcomes would most likely result?
A)One species will change its food preferences to eat insects andthe two species will coexist across both habitats.
B) Because of the abundance and diversity of food available, bothspecies will coexist across both habitats.
C) Both species will switch their diets to the more nutritiousinsects and one will exclude the other from both habitats.
D) No change will occur; the abundance and diversity of resourcesdoes not determine the ultimate outcome of competition if nichesremain the same.
