Apparent competition occurs when two species do not compete directly for the same resources but are linked through a common predator. In this context, if one species experiences an increase in population and subsequently attracts more predators, the other species may experience increased predation pressure even though they do not compete for the same food source. This scenario exemplifies how the negative impacts are derived from the shared impact of predation rather than direct resource competition. Therefore, the correct answer highlights the idea that the presence of a common predator creates a situation where the abundance of one species negatively affects the survival or population dynamics of another species, illustrating an indirect form of competition mediated by predation.
