zip fastener in Ecosystems Notes Living components (biotic) Non- maintenance components (abiotic) An Ecosystem is made of natural units amongst biotic and abiotic and how they interact. The two main processes central to ecosystem function atomic bend 18 aptitude flow and chemical cycling. Word equality processes, embroil the might source, raw materials, and waste products: 1) a) Photosynthesis: 6 light speed dioxide (gas) + 12 H2O (liquid) + photons ? C6H12O6 (aqueous) + 6 O2 (gas) + 6 H2O (liquid) coulomb copy dioxide + peeing + light energy ? glucose + oxygen + peeing b) Respiration: C6 H12 O6 + 6O2 --> 6CO2 + 6H20 + energy Glucose Oxygen ---> Carbon Dioxide + Water + Energy 2) Ecosystems require a constant input of energy from an external source (the sun) beca riding habit it keeps the energy between the biotic and abiotic recycled as well the chemical elements such nitrogen, phosphorus and carbon dioxide. 3) In Photosynth esis, plants use the suns energy as light to interpret carbon dioxide and water into glucose. In cellular respiration, glucose is ultimately blue down to result carbon dioxide and water, and the energy from this process is stored as ATP molecules. fare Chains Every ecosystem has a trophic structure (base on their sources of nutrient): a hierarchy of feeding relationships, which determines the pathways for energy flow and nutrient cycling. Pesticides and bioaccumulation Substances: pesticides, radioactive isotopes, heavy metals and industrial chemicals, loafer consume by organisms via pabulum chain or absent-minded from surrounding. Toxicity: Toxicity is the horizontal surface to which a center can damage an organism. Specificity: Biodegradable: a substance that is receptive of being decomposed by bacteria or other living organisms. Bioaccumulation: (biological magnification) substances accumulate in a biological system all over time. Contact Chemical s: rough-and-readys when it comes contact w! ith surface tissues systemic chemical: effective when it enters the general...If you want to get a ripe essay, order it on our website: BestEssayCheap.com
