Document Summary
All of the following about marine microbes are true except: Archaea dominate the shallowest 1000 m of the ocean. Prochlorococcus are common to oceanic gyres, environments classified as. This cyanobacteria lives in tropical and subtropical waters and is often responsible for algal blooms that can be seen from space. The presence of cyanobacteria increased the concentration of free oxygen. True or false: like bacteria, archaea are single-celled, yet they are more closely related to humans than bactera. Of the marine archaea, ______ account for 5-20% of the cells in deep or surface waters while ______ account for up to 40% of the prokaryotes in deep ocean waters. A molecule of ch4 is 25 times more potent than co2. As sea ice cover decreases, surface water of the arctic ocean could represent an important source of methane to the atmosphere. Methane cycling in the open ocean can have a direct impact on climate change at a regional and global level.
