    I HAVE COMPLETED MOST OF THIS ASSIGNMENT AND NEED HELP WITH THE LAST PART.

    Below is the complete assignment I have already completed everything except for the "Biogeochemical cycles describe the cycling and recycling of elements in ecosystems. In your own words, describe the cycling of carbon, phosphorus, and nitrogen through both the living (biotic) and non-living (abiotic) components of ecosystems. And, describe how humans have impacted each of these three cycles. " Here is website that has good information http://www.marietta.edu/~biol/102/ecosystem.html#BioGeoChemicalCycles8

    I am lost and I need someone to help me with this last part. Please Please help and I need the work to be original. HELP HELP HELP

    Describe the Industrial Revolution. How has it impacted the environment and the way that humans use natural resources?
    What triggered the Environmental Revolution? When did people become more focused on environmental issues? What are the goals of the Environmental Movement? Do you think that we should continue to pursue these goals? Why or why not?
    Biogeochemical cycles describe the cycling and recycling of elements in ecosystems. In your own words, describe the cycling of carbon, phosphorus, and nitrogen through both the living (biotic) and non-living (abiotic) components of ecosystems. And, describe how humans have impacted each of these three cycles.
    Please submit your assignment.

    Objective: Discuss fundamental concepts of Environmental Science: sustainability, stewardship, and sound science.
    Describe abiotic and biotic factors and their relationship to an ecosystem.
    Apply critical thinking skills to the content of the course.

    Questions 1 & 2. Describe the history and importance of the Industrial Revolution, and the Environmental Revolution. What are they? How have each of these impacted the natural environment and our perception of the natural world? Cite your sources.

    Question 2. There are many good resources that describe these three cycles, including your text, chapter 3. Please develop a one-paragraph summary for each cycle in your own words that briefly describes the cycle. How does each element (C, N, and P) move from the living to the non-living parts of the ecosystem. Then explain how human activity has impacted the natural cycles for each of these three elements. Cite your sources please.

    For this assignment, you need to write three paragraphs, one for each cycle. Let's take it one step at a time. Each element has separate cycling mechanism. But, all have some things in common. Remember, it's just a summary so don't get lost in the details. Because these are cycles, you can randomly pick a starting point. But, if you choose carefully it will be easier to trace the cycle. We can start with carbon.

    I suggest we start with carbon in limestone. This carbon is released by acidity in the water. It then goes either to the atmosphere or into the earth. The earth's carbon is supplemented by dying organisms. This carbon is released by humans when we burn fossil fuels (this is where humans are upsetting this cycle). The carbon released from the fossil fuel also goes into the atmosphere. There it is available to plants through photosynthesis. Some plants are eaten by animals, who incorporate the carbon into their bodies. Carbon in the atmosphere is absorbed by the oceans and ultimately by limestone, beginning the cycle anew.

    Solution Summary

    Description of the cycling of carbon, phosphorus, and nitrogen through both the living (biotic) and non-living (abiotic) components of ecosystems.
