Chapter 2: microbial ecology- production & decomposition of organic material (01/16/19 & 01/18/19) The global biological cycle involves the processes of photosynthesis and respiration to recycle carbon and other nutrients in the biosphere (fig. Photosynthesis creates organic material and releases heat (infrared radiation). Respiration uses the organic material created through the process of photosynthesis and recycles it into an inorganic material state. In the marine environment, prokaryotic microorganisms, primarily of the domains. Bacteria and archaea, dominate respiration due to their ability to undertake many forms of respiration and the sheer amount of non-living material available in the oceans. This cycle also includes processes, such as mineralization and decomposition to recycle nutrients. The functioning of the global biological cycle is to continuously remove and renew compounds needed for marine organisms to live. The global biological cycle receives input from many different chemical processes. Terms to know: eukaryote- an organism consisting of a cell or cells in which the genetic material is.
