What is an example of an ecological interaction?
Summary. Species interactions within ecological webs include four main types of two-way interactions: mutualism, commensalism, competition, and predation (which includes herbivory and parasitism). Because of the many linkages among species within a food web, changes to one species can have far-reaching effects.
What are five types of ecological interaction between organisms?
