Ques: Answer the following question given this paragraph: Herbivory has been used by seed plants for their own benefit in a display of mutualistic relationships. The dispersal of fruit by animals is the most striking example. The plant offers to the herbivore a nutritious source of food in return for spreading the plant's genetic material to a wider area. An extreme example of collaboration between an animal and a plant is the case of acacia trees and ants. The trees support the insects with shelter and food. In return, ants discourage herbivores, both invertebrates and vertebrates, by stinging and attacking leaf-eating insects. Q: How do seed plants benefit from herbivores? Choices: - radiation of seeds - consumption of seeds - rainfall of seeds - dispersal of seeds A:
Ans: dispersal of seeds
