Which of the following is NOT an outcome predicted by Lotka–Volterra competition model?

The keyed exception is “Species hybridization.” In the context of which of the following is not an outcome predicted by lotka–volterra competition model, that statement differs from the governing ecological pattern and must be evaluated against the mechanism rather than accepted from wording alone. Coexistence requires stabilizing differences that make each species limit itself more strongly than it limits its competitor, or an equalizing process that keeps fitness differences small. Without such mechanisms, persistent competitive asymmetry tends toward exclusion. The remaining alternatives—“S

Which of the following matches competitive exclusion?

“K1/α12 > K2 and K2/α21 < K1” for which of the following matches competitive exclusion. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Niche differentiation reduces overlap by separating species along resource, space, or time axes. Such partitioning can stabilize coexistence when each species performs relatively better under the conditions it uses most strongly. The remaining alternatives—“K1/α12 K1”, “K1/α12 > K2 and K2/α21 > K1”, “K1/α12 < K2 and K2/α21 < K1”—refer to different states, processe
