This leads to a reduction in fitness for both individuals, involve one species consuming the other; can result in continual co-evolution of traits in both species; responsible for stable cycling of the population sizes of both species, species lives on or in another species that it harms over time, sometimes resulting in host death; win for parasite, lose for host, similar to predation, but grazing interactions can be argued to provide a benefit because grazing can promote the growth of new plant material, affects prey abundance, restricts prey distribution, affects populations dynamics, community structure, major selection force, predators eat prey and reduce their numbers, predators go hungry and their numbers drop, more prey build up because lack of predators, increasing number of prey increases number of predators (population cycles of predators lag behind population cycles of their prey), (+/+): symbiotic; both species benefit from the interaction, vulnerable to cheating, where one pair in the interaction saves time or energy and circumvents the benefit to the other species, - Mutual and reciprocal evolution between two or more interacting species: exerts selective pressure on the other, so they evolve in response to each other, Set of physical and biological parameters that define the living requirements and living conditions of a species: response to competition and environmental change, competition for a resource through consumption, competition involving direct interaction between organisms, what can competition lead to in terms of niches, - Can lead to niche differentiation (competition most intense among organisms with similar niches, species divide a niche to avoid competition for resources, a count of the number of species in a community, how common versus rare those different species are.
