What chemicals do Nitrosococcus oceani and Nitrosopumilus maritimus consume from their ocean environment? How does the abundance of these chemicals influence their success and abundance? What is the relationship between nutrient availability and natural selection, in general? Nitrosococcus oceani and Nitrosopumilus maritimus are examples of single celled organisms which are part of the kingdom Archaea. They are totally separated from the bacteria and other organisms (Stewart, n.d.). They are very important for some of the natural processes in the environment especially for the nitrogen and methane cycle. They are also a major part of the biological and biomass processes Continue reading...
