Question

interspecific competition often leads to what disastrous outcome for the less fit species?

Explanation:

Interspecific competition refers to competition between different species for limited resources like food, space, or mates. According to the competitive exclusion principle (Gause's law), when two species compete for the same resources in the same niche, the more fit species will out - compete the less fit one. The less fit species will be unable to obtain enough resources to survive and reproduce. This leads to a decline in its population size over time. If the conditions of competition persist, the population of the less fit species may continue to decrease until there are no individuals left of that species in that area (local extinction) or the species ceases to exist entirely (global extinction).

Answer:

Extinction
