Document Summary
Biome: an ecosystem that exists over an extensive geographic range, occurring anywhere in the world that environmental conditions are suitable for its development. Each biome exists over an extensive geographic range, and it occurs anywhere in the world that the environmental conditions support its development. Life form: morphological and physiological traits of the dominant organisms. In marine biomes, dominant animals are the distinguishing feature, and physiological oceanography and nutrient supply are the key environmental influences. Convergent evolution has occurred because although they inhabit widely spaced places, the environmental conditions are similar and so therefore are the regimes of natural selection. Even though their ecosystems are structurally and functionally similar, biomes are not homogenous across long distances: biomes are characterized by their most extensive mature communities but they also contain other kinds of habitats. Key attributes are determined by the kinds of human activities that occur within and help to define them.
