Document Summary
Exploitation: interactions enhancing the fitness of the predator or herbivore, while reducing the fitness of the prey or host. Predation and herbivory influence distribution, abundance, and structure prey and host populations. Most species obtain resources through exploitative relationship with another species. Herbivory may stimulate plant growth, but also harms plants, reduces their plant growth and reproduction. Most plant matter is not exploited until death. Death arises from competition, abiotic stressors, or age related failings. Snow goose grazing and a sub-artic salt marsh. Wetlands inhabit herbivores whose feeding behaviour can change landscape (geese are domninant)
