In low-nitrogen conditions ucyn-a participates ina mutualistic symbiotic relationship with other organisms in the microbial mat. predict the most likley typre of symbiotic relationship between ucyn-a and the other organisms in the microbial mat if nitrogen becomes readily available from another source. provide reasoning to support your prediction

There are three distinct kinds of symbiotic associations, that is, commensalism, mutualism, and parasitism. In the given case, that is, when nitrogen becomes readily accessible from another source the UCYN-A will be in a parasitic relationship with other species and will be the obtaining food from them, as this species will not be able to perform the process of photosynthesis in order to generate its own food.  

In the parasitic association, one organism, that is, the parasite feeds off of another organism, which is considered as the host, harming it and probably resulting in its death. The parasite thrives on or in the body of the host.
