I can't see images A and B, so I can't provide a direct analysis of the traits between the micro-organisms depicted in them. However, to determine if a micro-organism in image A is considered a living organism, it typically must exhibit characteristics such as cellular organization, metabolism, growth, reproduction, and response to stimuli. If it lacks these traits, it may be classified as a virus or similar entity, which are not considered living organisms.
Please provide a description of the images, and I'd be happy to help analyze the differences and the living status of the organisms presented.
