Life on our planet is made up of an incredible variety of carbon molecules, and, in essence, life processes are carbon chemistry. Conversely, the carbon cycle, which can be viewed as the movement of carbon atoms through various places of storage on Earth, called reservoirs, is intimately tied to life processes.xamples of reservoirs are the ocean, the atmosphere, the biosphere, the soil carbon, the carbonate sediments, and the organic carbon sediments.. The fluxes between them describe the rate at which atoms move from one reservoir into another.
A loan agreement is: 1  A borrower's written promise to repay a sum of money, or principal, to the lender.  A document that outlines the terms of a loan, including a repayment plan, between a lender and a borrower.
Loans from banks or other institutional lenders are always made using a number of documents, two of which are a promissory and security agreement. In general, the promissory note is your written promise to repay the loan and a security agreement is used when collateral is given for the loan.
