According to the competitive exclusion principle, the populations of two species that live in the same place and have exactly the same ecological requirements
A) can coexist at the same carrying capacity (K) as when each population is separate. B) can coexist but with the population of each species at half of the carrying capacity (K) as when each population is separate.
