expertness in Ecosystems Notes Living components (biotic) Non- life history 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 do 18 aptitude flow and chemical cycling. Word equation processes, embroil the brawniness source, raw materials, and waste products: 1) a) Photosynthesis: 6 coke dioxide (gas) + 12 H2O (liquid) + photons ? C6H12O6 (aqueous) + 6 O2 (gas) + 6 H2O (liquid) coulomb copy dioxide + peeing + light energy ? glucose + oxygen + egest 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 international 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 Photosynthe sis, plants use the suns energy as light to veer carbon dioxide and water into glucose. In cellular respiration, glucose is ultimately miserable 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, green goddess consume by organisms via pabulum chain or heed less from surrounding. Toxicity: Toxicity ! is the horizontal surface to which a vegetable marrow can damage an organism. Specificity: Biodegradable: a substance that is undefendable of being decomposed by bacteria or other living organisms. Bioaccumulation: (biological magnification) substances accumulate in a biological system everywhere time. Contact Chemicals: utiles when it comes contact with surface tissues systemic chemical: effective when it enters the general...If you want to get a ripe essay, order it on our website: OrderCustomPaper.com
