Select an Answer

Decomposers (e.g., bacteria)

Correct Answer: 
Yes

Producers (e.g., grasses)

Correct Answer: 
No

Primary consumers (e.g., mice)

Correct Answer: 
No

Secondary consumers (e.g., snakes)

The correct answer is Decomposers (e.g., bacteria). Of the list of organisms given, decomposer bacteria are the only ones that can convert nitrogen-containing organic molecules into ammonia. Ammonia, which is a form of nitrogen-containing molecule, is subsequently converted to nitrate that plants can use to synthesize new organic compounds with nitrifying bacteria.
