Document Summary
The players: what organisms are involved in decomposition. Succession of fungi: what happens @ these creatures gone. Measuring decomposition: measuring the rate of____: break down of the chemical bonds within complex organisms, opposite of photosynthesis: Biogeochmniacal cycle compounds and matter getting passed around. Water that runs off from land -> goes to the ocean. Water evaporates and makes it super salty. ~ respired eaten by animal or can be decomposed. Co2dissolves easily in water,, phytoplankton uses the carbon and compresses it~ Crash course nitrogen and phosphorus: air mainly nitrogen, rocks are usually just a bunch of phosphorus, ammonia becomes ammonium ( nh3 nh4 when mixed with water, nitrogenase used to break the crazy triple bond. Nitrifying bacteria take the ammonia and turn it into nitrate no3. Denitriying take the no3 and turn it back into nitrogen gas// uses nitrate reductase.
