Document Summary

A. ecosystem: ecosystem- all living organisms in an area together with abiotic environment. B. key concepts (important: figure 55. 4: e flow is linear, vital materials recycled. C. e flow: linear, 1st law of thermodynamics- cannot be created nor destroyed, only transferred and transformed -> sunlight in, heat out, radiant e -> ~1% stored -> broken down, used -> heat escapes. D. matter: law of conservation of mass- matter cannot be created nor destroyed, must move through ecosystem -> biogeochemical cycles, movement of living and nonliving matter of the environment, nutrients cycling requires producers and decomposers (figure 55. 3). A. primary production: primary production- amount of light e converted to chemical e by autotrophs during a given time. B. gross primary production: gross primary production (gpp)- total primary production in an ecosystem, or amount of e converted to chemical e of organic molecules per time, producers need e, too!
