All living organisms share many characteristics necessary for life. for example, all organisms, including both prokaryotic and eukaryotic, a. can use abiotic factors to make their own food. b. can sexually reproduce to produce unique offspring. c. have cells arranged into complex organ structures. d. must obtain and use energy for life processes.

The correct answer is option D. Both prokaryotic and eukaryotic organisms must obtain and use energy for life processes. Obtaining & using energy is an absolute necessity of a living organism without which no organism can survive, be it prokaryotic or eukaryotic. Option B is incorrect because only eukaryotes reproduce sexually while the mode of reproduction in prokaryotes is either asexual or para sexual. Option C is also incorrect because only eukaryotes have cells arranged into complex organ structures. Option A is correct because both eukaryotes and prokaryotes can use abiotic factors to make their own food.
