1. THE ROLE OF MICRO-ORGANISIMS IN CARBON CYCLE BY WALLACE MUKOKA

2. Microbes live almost everywhere on Earth including within and on other living organisms. Many fungi and bacteria are essential for cycling nutrients in ecosystem and for acting as decomposers, breaking down dead organisms and the waste of living things. Microbes plays a vital role in bio- geochemicals cycles such as the nitrogen cycle, sulphur cycle and the cardon cycle.

3. Micro-organisms are microscopic organisms, which may exist in its single-celled form or in a colony of cells for Examples fungi, bacteria, algae, protozoa, archaea. Biogeochemical cycle is The flow of chemical elements and compounds between living organisms and the physical environment. Chemicals absorbed or ingested by organisms are passed through the food chain and returned to the soil, air, and water by such mechanisms as respiration, excretion, and decomposition.

4. Carbon cycle The carbon cycle is the series of processes by which carbon from the environment is incorporated into living organisms and returned to the atmosphere as carbon dioxide. Carbon is circulated as one of three forms, carbon dioxide, methane and organic compounds.

5. Bacteria and algae [photosynthesis and respiration ] Plants and Phytoplankton (microscopic organisms in the ocean) and plants take carbon dioxide from the atmosphere by absorbing it into their cells. They use energy from the Sun, both plants and plankton combine carbon dioxide (CO 2 ) and water to form sugar (CH 2 O) and oxygen. The chemical reaction looks like this: CO 2  + H 2 O + energy = CH 2 O + O 2

6. Plants break down the sugar to get the energy they need to grow. Animals (including people) eat the plants or plankton, and break down the plant sugar to get energy. Plants and plankton die and decay (are eaten by bacteria) then oxygen combines with sugar to release water, carbon dioxide, and energy. The basic chemical reaction looks like this: CH 2 O + O 2  = CO 2  + H 2 O + energy

7. This diagram of the fast carbon cycle shows the movement of carbon between land, atmosphere, and oceans. Yellow numbers are natural fluxes, and red are human contributions in gigatons of carbon. White numbers indicate stored carbon .
