How Do Consumer–Prey Interactions Shape Evolutionary Adaptations?
Once a mutualistic relationship evolves between two species, will natural selection and co-evolution cause the two species to become continuously more dependent on each other? Or is it possible for one to end the mutualism? Describe.
Two different species cannot occupy the same niche in the same geographic area. If they do they will compete with one another for the same food and other resources. Eventually, one species will out compete the other. This is an example of natural selection.
A) True
B)Â False
