A scientist cultures the dried soup from a 4,000-year-old cooking pot found in an Egyptian tomb and obtains a distinctive species of prokaryote. She immerses a test tube of these bacteria in boiling water for several hours, but the colony grows back. This species is probably.

Endospore-forming.

Explanation:

Prokaryotes may be defined as the organism that lacks the nucleus and membrane bound cell organelles. Prokaryotes are smaller in size and simple as compared with eukaryotes.

The endospore formation occur in some species of prokaryotes. Endospores are hard, tough covering of the spores to protect them from the harsh environmental conditions. The colony can grow back this means the species has the ability form endospore.

Thus, the answer is endospore forming.  

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.
