BIOL 110 Lecture Notes - Lightning, Nitrite, Haber Process
Document Summary
Elements are taken up by producers (plants) / stored as organic matter. Passed on across trophic level / consumer digest and absorb food / stored as organic matter. Decomposers decay detritus and excretory products / return inorganic ions to environment / taken up by producers. Warm temp / higher enzyme activity / faster decomposition. Table 9-14-1: use of nutrients in plants and animals. Nitrate reductase / reduces nitrates during synthesis of amino acids. Organic substances / lipids / proteins / atp / chlorophyll. Needed for enzymes such as catalase to work. Producers, consumers, decomposers: add co2 to the air by respiration, carbon is stored in tissues as organic matter (carbohydrates, lipids, proteins, carbon is passed along food web by feeding. Plants remove co2 from air by photosynthesis. Decomposers decay detritus and excretory products / add carbon to soil: detrivores digest detritus to small pieces / large surface area, saprophytes digest smaller detritus by.
