Document Summary
We"re currently living in 6th mass extinction (era?) Iron = important nutrient and often is implicated in major swings according to the climate like ice ages. Fisheries), invasive species, pollution, climate change (often in addition to other risks of biodiversity: wealth correlated with co2 emissions. Carbon, nitrogen: biochemical cycles = the movements of elements between the living and nonliving parts of the. Carbon pollution = ones of greatest threats. Zachos curve = history of temperture of earth: iron cycle. Fe = important nutrient in ocean and terrestrial ecosystems. Largest source of it is atmospheric deposition (aka windblown dust) Each biome many ecosystems whose communities have adapted to the small differences in climate and the environment inside the biome.
