Terms in this set (36) Consequences of herbivory for plants - not necessarily lethal - loss of growth potential - coevolution plant and herbivore. Due to their large surface area, their absorptive nutrition mode and their immobility, fungi are highly susceptible to bacterial competitors and animal predators and, still, their defense mainly relies on chemical defense.

Seed predation, often referred to as granivory, is a type of plant-animal interaction in which granivores (seed predators) feed on the seeds of plants as a main or exclusive food source, in many cases leaving the seeds damaged and not viable. While some predators will eat prey animals whether they are alive or dead, others don’t like to eat dead animals.
