of Environmental Science. Describe the trophic levels presented in the diagram. Explain what is meant by a producer, first-order consumer, and second-order consumer. In the diagram of the food chain, the arrows show how energy flows from one level to another. The green plants are the producers because they food are produced by the process of photosynthesis by using sunlight, water and carbon of the food chain. The second order consumers are carnivores because the herbivores are their food. Therefore, carnivores are in the second-order consumer because they depend on the first-order consumer to produce energy. * Review Figure 4-12, "Energy pyramids in two food chains" in Ch. 4 of Environmental Science. The figure description states, " ...more food is available to those societies that eat lower on the food chain". Explain what this means by comparing pyramids (a) and (b). Do the benefits of eating lower on the food chain inspire you to make changes in your diet? Why or why not? As it shows in the diagram, the most energy is gain from food at lower levels of the food chain. For instance, it the higher levels of the pyramid 10% are the only amount of energy that is transferred from one level to the next. In the case of the lower trophic levels provide and transfer the higher energy. Therefore, the energy transfers decrease as the level increase or get higher. The consumption of more producers in the lower levels should be consumer by the higher trophic levels so that more energy transfers in the consumption process. Therefore, the benefits of consumer food from the lower level of the food chain has inspired me to make changes necessary in my diet because I start consumer more food from the lower levels my energy will increase. * Review Figures 4-13 and 4-14 in Ch. 4 of Environmental Science. Summarize the steps of the carbon cycle.
