4. Component Two In diet one, you see a cow that is consuming grass, then being consumed by a human. When being a higher level consumer, you lose food energythrough energy transfers. In diet two, you see plants being produced then being eaten by humans. When you eat less meat, you tend to have a higher energy transfer. As energy passes through a higher trophic level, you lose up to 90% of the useful energy. In moving to the next trophic level, only 10% of the original energy is available; by the third trophic, you are only able to use up to 1% of the original energy. Emissions that are given off from cows are much more dangerous than those given off by cars. For example, when you burn fuel to make fertilizer which grows feed, then produces meat and is then needed to be transported- produces 9% of all emissions of carbon dioxide*. Methane gas is another green house emission. When dealing with cows, their manure releases more than one third of the methane emissions. Carbon dioxide*- most common greenhouse gas http://www.independent.co.uk/environment/climate-change/cow-emissions-more-damaging-to-planet-than-co2-from-cars-427843.html http://www.elmhurst.edu/~chm/vchembook/321foodenergy.html
