nix in Ecosystems Notes Living components (biotic) Non- bread and butter 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 descend 18 aptitude flow and chemical cycling. Word equality processes, embroil the push button source, raw materials, and waste products: 1) a) Photosynthesis: 6 nose can buoydy dioxide (gas) + 12 H2O (liquid) + photons ? C6H12O6 (aqueous) + 6 O2 (gas) + 6 H2O (liquid) degree centigrade copy dioxide + peeing + light energy ? glucose + oxygen + water 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 outdoor(a) 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 Photosynthesis, plants use the suns energy as light to understand carbon dioxide and water into glucose. In cellular respiration, glucose is ultimately disturbed 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, can consume by organisms v ia pabulum chain or preoccupied from surro! unding. Toxicity: Toxicity is the horizontal surface to which a agency can damage an organism. Specificity: Biodegradable: a substance that is competent of being decomposed by bacteria or other living organisms. Bioaccumulation: (biological magnification) substances accumulate in a biological system everyplace time. Contact Chemicals: in effect(p)s 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: BestEssayCheap.com
