They obtain nutrients by absorbing organic material from their environment (decomposers), through symbiotic relationships with plants (symbionts), or harmful relationships with a host (parasites). Which of the following is an accurate statement about prokaryotes? Most of them are bacteria, while some are very primitive eukaryotes. One common example of a halophile is Halobacterium. They produce energy and metabolites using different chemicals since their cells lack cellular organelles such as chloroplasts, nuclei, and mitochondria that perform these functions. Although all cells have organelles in common, the number and types of organelles present reveal how the cell functions. A group of eukaryotic organisms consisting of the flatworms and roundworms, which are collectively referred to as the helminths. As part of this process, a change in levels of selection occurred, with selection at the multicellular level overriding selection at the cell level.
