PROJECT: PURCHASING A NEW TRACTOR Mr. Ben Gower is a farmer in Wisconsin, raising string beans for a nearby canning company. To be more environmentally sound, he is considering purchasing a new tractor to get his daily work done. He is looking at a couple of different models, including a fancy one that does just about everything. You are called in to be a consultant to Mr. Gower. Using manufacturers' websites (John Deere, Case International, or others), select three tractors that are equivalent in the amount of work they can do. They need to be able to plow, harvest, run GPS, have onboard computer navigational systems, and have low emissions to meet the EPA's directive on reduced oxides. Set up a spreadsheet that compares 12 different features of the tractors, and then make a recommendation to Mr. Gower based on your research.

your answer is true

explanation:

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
