I NEED SOME SUPER SMART SCIENCE WHIZ TO HELP ME 10 POINTS?

  • i need some help guys, my teacher wanted me to write one paragraph about the carbon cycle, but unfortunately i dont understand it can you please help me?I really need the help because i know somewhere out there someone knows the answer, i just need them to share it, i asked my whole family to help me but they dont know nothing, if i get one more F my overall grade for science will drop to a D :( the question goes like this "Write one paragraph essay on the carbon cycle, pretend you are a carbon atom that is recycled.Include the following words: photosynthesis,feeding,respiration, decomposition,deposition(define), human activity" please help a guy out

  • Answer:

    The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. It is one of the most important cycles of the earth and allows for carbon to be recycled and reused throughout the biosphere and all of its organisms. The carbon cycle was initially discovered by Joseph Priestley and Antoine Lavoisier, and popularized by Humphry Davy. It is now usually thought of as including the following major reservoirs of carbon interconnected by pathways of exchange: The atmosphere The terrestrial biosphere, which is usually defined to include fresh water systems and non-living organic material, such as soil carbon. The oceans, including dissolved inorganic carbon and living and non-living marine biota, The sediments including fossil fuels. The Earth's interior, carbon from the Earth's mantle and crust is released to the atmosphere and hydrosphere by volcanoes and geothermal systems. The annual movements of carbon, the carbon exchanges between reservoirs, occur because of various chemical, physical, geological, and biological processes. The ocean contains the largest active pool of carbon near the surface of the Earth, but the deep ocean part of this pool does not rapidly exchange with the atmosphere in the absence of an external influence, such as a black smoker or an uncontrolled deep-water oil well leak. The global carbon budget is the balance of the exchanges (incomes and losses) of carbon between the carbon reservoirs or between one specific loop (e.g., atmosphere ↔ biosphere) of the carbon cycle. An examination of the carbon budget of a pool or reservoir can provide information about whether the pool or reservoir is functioning as a source or sink for carbon dioxide.

Define the two words carbon and cycle. Carbon is an element and cycle means repeat or turn in a circle. It is a vicious circle for plants and animals and carbon is the carrier.

Hi

The carbon cycle is the The movement of carbon, in its many forms, between the biosphere, atmosphere, oceans, and geosphere is described by the carbon cycle The carbon cycle is one of the bio-geochemical cycles. In the cycle there are various sinks, or stores, of carbon and processes by which the various sinks exchange carbon. We are all familiar with how the atmosphere and vegetation exchange carbon. Plants absorb CO2 from the atmosphere during photosynthesis, also called primary production, and release CO2 back in to the atmosphere during respiration. Another major exchange of CO2 occurs between the oceans and the atmosphere. The dissolved CO2 in the oceans is used by marine biota in photosynthesis. Two other important processes are fossil fuel burning and changing land use. In fossil fuel burning, coal, oil, natural gas, and gasoline are consumed by industry, power plants, and automobiles. Notice that the arrow goes only one way: from industry to the atmosphere. Changing land use is a broad term which encompasses a host of essentially human activities. They include agriculture, deforestation, and reforestation HOPE YOU CAN FIND THE ANSWER IN THIS
