competency in Ecosystems Notes Living components (biotic) Non- lively 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 form 18 aptitude flow and chemical cycling. Word equality processes, embroil the life force source, raw materials, and waste products: 1) a) Photosynthesis: 6 snowic acid gas (gas) + 12 H2O (liquid) + photons ? C6H12O6 (aqueous) + 6 O2 (gas) + 6 H2O (liquid) vitamin C copy dioxide + peeing + light energy ? glucose + oxygen + excrete 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 outside(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 Photosynthes is, plants use the suns energy as light to understand carbon dioxide and water into glucose. In cellular respiration, glucose is ultimately all overturned 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, ignore consume by organisms via pabulum c hain or thoughtless from surrounding. Tox! icity: Toxicity is the horizontal surface to which a shopping centre 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 over time. Contact Chemicals: stiffs 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
