Which of the following mutualistic relationships have the largest impact on population dynamics?

Question

Quizplus · Accepted Answer

Obligate mutualistic relationships involve species that depend on each other for survival, and therefore have a larger impact on population dynamics. The loss or decline of one species can have significant effects on the other. Generalist pollinators, nitrogen-fixing bacteria, and seed-dispersing animals may have important roles in ecosystem function, but they may have less impact on population dynamics compared to obligate mutualists.
