Which of the following organisms feed on the detritus found in wetlands? a. aquatic insects b. birds c. reptiles d. predatory fish

I think the correct answer from the choices listed above is option A. Aquatic insects are the insects that feed on the detritus found in wetlands. Detritus are organic matter that is produced by decomposition and most likely in wetlands insects that are aquatic feed on these matter.

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.
