Answer 3

medal please

Answer 4

thanks

Answer 5

@My_Yich so first you need to understand what info you are given. A prokaryote is a single celled organism. So this single-celled organism is living near a volcanic vent deep in the ocean.

A photoautotrophs. This has the prefix "photo" meaning it needs sunlight to survive. There will be no sunlight for our organism to live off of, if it is living deep in the ocean. A is not the answer.

B. Chemoautotroph. This is an organism that has the ability to use inorganic materials to make organic food for itself. In the definition it actually says that these can be found specifically in the deep ocean around volcanic vents. B is the correct answer.

C. Heterotroph. This is an organism that cannot make its own carbon and therefore must use carbon provided by autotrophs. They are not usually found deep in the ocean. This is not the correct answer.

D. photoheterotrophs. This has the prefix "photo" meaning it needs sunlight to live. Once again sunlight will not be found deep in the ocean, so this is not the correct answer.

Sorry this is so long, but I hope it gives you a better understanding of the material. ~Bree :) p.s maybe a medal please? if not its cool :)
