Biogeochemical cycles recycle water and natural elements throughout the biosphere to ensure that organisms do not run out of these substances. diagram by nasa/kevin saff diagram by ilmari karonen which of the following processes plays an important role in cycling carbon, nitrogen, and phosphorus? photosynthesis transpiration decomposition respiration

The process that is vital in the recycling of carbon, nitrogen and phosphorus is decomposition.
During decomposition, organic matter from dead organisms is broken down. This break down yields simpler and smaller substances from the more complex ones that were present in the organism.
Carbon is released from the carbohydrates and fats that were present in the organism. Nitrogen is released from the proteins that were present and phosphorus is released from the nucleic acids.

This bacteria must be very strong as it has a large amount on antibiotic targeting it. this bacteria could be one of many different types and it is very hard to tell which one with out more information.
