Document Summary
Producers trap ~1% of solar energy by photosynthesis: cellular respiration energy rich molecules are broken apart. Energy in the form of atp available for cell to do work. Energy from food passes from one organism to the next (linear flow through. Release simple inorganic molecules (carbon dioxide, organisms matter) litter, feces) mineral salts) Used by producers: essential to recycle organic matter, earthworms, fungi, prokaryotes, food webs model of trophic relationships. Shows flow of energy and materials through ecosystem. Some of this energy will be used by producers during cellular respiration. Ra = autotrophic respiration: amount of energy that remains in tissues after cellular respiration, stored chemical energy that is available to next tropic level. 3rd trophic level = secondary and tertiary consumers. Energy transfer between trophic levels: secondary production amount of chemical energy in consumers" food that is converted to their, production efficiency own biomass.
