Competition, Predation and Symbiosis
Climax Communities | Biology | Ecology
This video on Competition, Predation and Symbiosis 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.
