Q4. If four different snake species with identical food and habitat niches colonize an island at the same time, and one is better able to detect and acquire food than the others, which of the below options will most likely happen over time? The species best able to detect and find food will compete with the others, causing them to occupy smaller realized niches. k The species best able to detect and find food will outcompete the other snakes; it will eliminate the others via competitive exclusion. All four species will coexist because they will all occupy smaller realized niches due to competition. One species will persist, but we cannot predict which one; the others will go extinct because of competition. Submit Q5. Kangaroo rats are endemic to the deserts of the American southwest. In one region, two kangaroo rat species eat only seeds and are biologically extremely similar. The two species are found in adjacent habitats. Seeds are abundant in both habitats, but less nutritious than insects. If you were to double the amount of seeds across both habitats and add insects as potential food, which of the following outcomes would most likely result? One species will change its food preferences to eat insects and the two species will coexist across both habitats. Because of the abundance and diversity of food available, both species will coexist across both habitats. Both species will switch their diets to the more nutritious insects and one will exclude the other from both habitats. No change will occur, the abundance and diversity of resources does not determine the ultimate outcome of competition if niches remain the same.
