Question

Prokaryotes can be divided by the way they obtain energy and nutrients. Which of the following correctly matches the name of a group of prokaryotes with the source of their energy and nutrition?aChemoautotrophs—from sunlight through photosynthesisbHeterotrophs—from molecules that contain sulfur or nitrogencPhotoautotrophs—from sunlight through photosynthesisdChemoautotrophs—from other organisms

Answer 1

Chemoaotrophs are organisms that obtain energy from inorganic molecules, they are able to use chemicals that are good electron donors, such as hydrogen, sulfur, or iron.

Heterotrophs are organisms that obtain energy from other organisms, i.e. they are organisms that eat plants or animals to live.

Photoautotrophs are organisms that obtain energy from light, these organisms are also called photosynthetic organisms.
