Match the following biogeochemical cycles terms to the correct definiton. In this cycle the absorption of this 1. bio-essential element from the atmosphere increases the pH of the oceans. The main reservoir of this nutrient 2. is in the building block for all necessary biomolecules (fats, proteins, and carbohydrates) that constitute an important part of the inorganic matter. The element of this cycle is stored 3. in long-term in Carbonate rocks (e.g., limestone) And Fossil carbon (e.g., oil, coal) SInk The material flows in from the 4. reservoir. Source The reincorporation of this 5. element in its cycle is slow Carbon cycle because a considerable amount of it is stored in animal epidermal Phosphorus cycle alpha-keratin protein filaments. In this cycle the fungi from 6. Nitrogen cycle the Rhizobium family helps in the fixation of this element into the soil. Most plants cannot access this 7. nutrient from the atmosphere; therefore, they obtain it from the soil. This cycle refers to a 8. macronutrient that is essential for metabolic energy use as ATP. An example of this concept is a 9. coal-fired power plant release more carbon dioxide into the atmosphere than it absorbs.

Draw out the Nitrogen cycle; label nitrogen fixation, decomposers, ammonium, nitrates, uptake by plants, nitrogen in the atmosphere, detritus.

Which of the following statement is INCORRECT?A. Bacteria can decompose organic nitrogen.B. Biological nitrogen fixation is carried out by bacteria.C. Ammonia, ammonium ion and nitrate ion are examples of biological availablenitrogen.D. Denitrifying bacteria converts atmospheric dinitrogen gas into nitrate ion.E. Nitrification is the process of converting reactive nitrogen into another form ofreactive nitrogen.
