Some microorganisms reside in soil and on plant roots and undergo a process called nitrogen fixation which turns nitrogen from the atmosphere into compounds that are absorbed by plants. What best describes the role of the microorganisms? A The microorganisms disrupt the health of organisms in the ecosystem. B The microorganisms aid in the processes of decomposition. C The microorganisms aid in the cycling of nutrients in the ecosystem. The microorganisms cause disease in plants and animals.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
