Simutext Decomposition with complete solutions|100% pass

what is decomposition breakdown of organic matter into simpler inorganic forms and associated release of energy what distinguishes us from other decomosers we eat dead food, release energy through chemical and physical means, some organisms specialize in organisms they did nto kill 00:09 01:28 tree of interest insect of interest hemlock trees- N amaerica and asia (lots of rain and cool temp) woody adelgid- minor pest how fast is woody adelgid moving? why is this bad 20 miles per year hemlock provides food/cover for fish, birds, mammals decomposition of hemlocks needs to keep up (litter quality changes) what affects decomposition rate 3 factors: temperature and moisture and litter quality (type of matter) how do decomposers undo photosynthesis photosynthesis pulls carbon respiraion of decomposers release back to atmosphere and nitrogen/phosphorus what is leaf that is kinda overtaking hemlock tulip poplar rhododendron ease of decomposition relates to liter quality high litter quality means easy to eat food for decomposers 3 main drivers of decomposition triangle litter quality climate decomposer organisms organic compounds are carbon conatining, synthesized by living organisms carbon moving around in an ecosystem is known as the carbon cycle 00:00 01:28 main carbon source is carbon dioxide in atmosphere purpose of plants primary producers that capturs atmospheric co2 during photosynthesis and combine with solar energy and water to make carbohydrates decomposition is the same equation as respiration the reactions to help oxygen reach a lower energy state are known as redox reactions why are decomposition reactions aerobbic what is other option they require oxygen when oxygen is used up, decomposers use anaerobic forest of interes Coweeta forest- wet what compounds are monitored what is set up of experimetn co2 and ch4 one sealed container one open which is faster... aerobic or anaerobic what is gas produced aerobic is more efficient methane microorganisms are either aerobic or anaerobic specialists first step of anaerobic carbs and proteins undergo hydrolysis to make soluble compounds (sugars and amino acids) second step of anaerobic soluble compounds undergo fermentation to release CO2 and create organic acids (carboxylic and carbonic acid) third step of anaerobic organic acids (carboxylica nd carbonic acids undergo methanogenesis to release methane and co2 what does fermentation bacteria and yeasts anoxic decomposition is decomposition where oxygen is only present within sulfites, nitrates, nitrites release sulfur/nitrogen gas and Co2 where does anoxic decomposition occur waterlogged nitrate rich sediments like salt marshes and mangrove what is converted to what in fermentation sugars to alcohol and carbon dioxide chemicals in wine and beer barley, wheat, rice, hops, grapes produe ethanol and co2 from fermentation
