Question

1. if the number of nitrifying bacteria decreased what effect would this have on the nitrogen cycle and what type of compounds would accumulate as a result? 14. plants and animals (and all other living things) are part of all the natural cycles through food chains and food webs. name the four classes of carbon - containing molecules used by living things, and explain how the nitrogen and carbon cycles contribute to the usable supplies of these macromolecules.

Explanation:

Step1: Recall the role of nitrifying bacteria

Nitrifying bacteria convert ammonia to nitrites and then to nitrates in the nitrogen - cycle.

Step2: Analyze the consequence of decreased nitrifying bacteria

If nitrifying bacteria decrease, ammonia (NH₃) will accumulate since there are fewer bacteria to convert it to nitrites and nitrates.

Answer:

Ammonia would accumulate.
