Document Summary

Climate is a measure of the average pattern of variation in temperature, precipitation( ), and other meteorological( ) variables in a given region over long periods of time. Biomes( ) the world"s major communities, classified according to the predominant vegetation and characterized by adaptations of organisms to that particular climate. Chapparal temperate shrubland( ) and woodland; hot, dry summer; cool, moist winter; dense vegetation, vulnerable to summer fires. Plant---adapt to: drought((cid:12545) )---summer--hot dry--drought resistant thick leaves, leathery, small-- >minimize the amount of water loss: evergreen( / (cid:12547) )--light throughout the years--photosynthesize throughout the years. During wet cool period, have a lot of growth, but in the dry hot period, the growth becomes dry, provide fuel for fire. Evolve to deal with( )---rely on fire to do reproduction. Plants evolve to deal with fire--some rely on fire--complete reproduction. Because the competitive vegetation are burnt away--bare soil exposed(mineral rich)--seeds can easily fall in place and germinate without competition.
