Document Summary
Adaption examples: caribou leg: organisms are adapted to deal with low temperatures. Adaptions are inherited for organisms to deal with weather conditions, Corals: algae and symbiosis based on a number of factors; increase in temperature and acidity, inject their algae, prevents them from growing, no source of energy. Change in temperature in 1 degree warmer for corals in an entire area to turn white. Adapted to a a particular ocean temperature- range of temperature is narrow, if it goes above that range, corals are unable to adapt, this means the whole ecosystem will disappear. Buller"s albatross: come out of the ocean to breathe, can live decades, live in the southern hemisphere, mate for life. Black-capped chickadee: seen all year, quite common, three years old- ancient, don"t live that long. Even in plants we can see characteristics than can span a wide range of differences in terms of adaptations.
