Final answer:
Species with similar resource usage but very 1) different carrying capacities are more likely to coexist, as competition is minimized, allowing for possible niche differentiation.
Step-by-step explanation:
Based on the Lotka–Volterra equations, which deal with species interaction and their population dynamics, we can infer about carrying capacity and species coexistence. The statement that is most likely true is that species with similar resource use but very different carrying capacities are more likely to coexist than species with similar resource use and similar carrying capacities. If two species have similar carrying capacities and compete for the same resources, they can exert additional pressure on each other, which might reduce the likelihood of their coexistence. However, if their carrying capacities are very different, it is possible that they could find a balance or a niche that allows both to survive with minimal competition. Doubling the carrying capacities of two competing species may not necessarily increase the likelihood that the species will coexist, as it does not change the fact that they compete for the same resources; it simply means there are more available resources temporarily. The carrying capacity is dynamic and can vary due to environmental factors and competition, which includes both intraspecific and interspecific competition. Natural events, as well as the presence of other species, can alter an environment's carrying capacity and the outcomes of species competition.
