 		Our Competition, Predation and Symbiosis DVD first describes the concepts of community, coevolution and ecological niche before looking at how competition results from overlapping niches. The program then examines predator-prey relationships and the various adaptations such as camouflage, warning coloration, mimicry and chemical warfare that have evolved as a result of these relationships. Symbiotic relationships such as parasitism, commensalism, and mutualism are then explored. A discussion of primary and secondary succession concludes the program.
