Bacteria are responsible, in some way, for all but one of the processes in earth's environment. that is
a) photosynthesis.
b) phosphorylation.
c) recycling carbon.
d) nitrogen fixation.

B. Phosphorylation A bacteria can do all of the following 1. Photosynthesis 2. Recycling carbon which contributes to carbon cycle 3. Nitrogen fixation which contributes to nitrogen cycle These three indicated functions are significant because they perform specific contributions in the biosphere. Phosphorylation is a function which is part of the ATP process and has nothing to do with bacteria.
