Document Summary
Competition- when multiple organisms are seeking the same limited resource. Biomimicry- the examination of nature, its models, systems, processes, and elements. Parasitism- when an individual from one species uses another species to benefit oneself without harming the host in any way. Macro- invertebrates, fungi: hemi parasitic- take water and nutrients from the host, example- sea lamprey. Social parasite- don"t eat things, manipulates the hosts behaviour. Amensalism- one organism is harmed and the other is unaffected. Commensalism- one species benefits and the other is unaffected. Keystone species- species with an especially strong impact, holds structure together. Pioneer species- lichens: best suited for colonizing on bare rock. Climax community- resolved community stays intact until next succession. Invasive species- produce disturbance and often lead to succession. Forests- trees close enough together that their crown touch. Savannah- scattered trees in a grassy or shrubby area. Grassland- grasses and other herbs, trees sparse. Thicket- tall shrubs or small trees close together.
