5 basic types of predation - carnivory, parasitism, parasitoids, cannabalism, herbivory Abiotic components - non-living chemical and physical factors(temperature, light, water, nutrients) ammensalism - one species is harmed and the other is unaffected(-,0) ex: larger tree shading smaller stature tree aquatic vs. terrestrial systems - terrestrial--> 3 trophic levels(odd number=resource limitation) aquatic--> 4 trophic levels(even number=consumer limitation) Aristotle - Historia anima...
