Hi, everyone. Let's take a look at this practice problem together which of the following groups of micro organisms is matched incorrectly with its description. The answer options are a Archia often thrives in extreme environments. B protozoa primarily multicellular and are autotrophs c algae and producers in the aquatic environment and D viruses, noncellular infectious agents. So let's jump right into the answer. Options. Option A archia recall are prokaryotic cells and these cells can survive in high salt or high heat environments. Thus, the archaia do thrive in extreme environments. So option A is incorrect option C recall that algae are you Karic photo synthesizers, algae are found readily in both fresh and salt water. So algae are producers in the aquatic environment and option C we can eliminate. Option D viruses recall are not cells and only contain a core made up of one type of nucleic acid. So viruses replicate by using an organism, cellular machinery and they are infectious. So option D is also correctly matched. So it cannot be the correct answer. The incorrectly matched pair is option B. So protozoa recall our single cell eukaryotic microbes, they mainly absorb organic matter from their environment which means that they are heterotrophic. Some protozoa do use photosynthesis but they are not multicellular and they are not all autotrophic. So the correct answer is option B protozoa primarily multicellular and are autotrophs. All right, everyone. I hope you found this helpful and I'll see you soon for the next practice problem.
