Question

2 mark for review the table above shows the balanced chemical equations that represent three processes that are part of the nitrogen cycle. which of the following is exemplified by the equations above? a approximately 10% of energy is transferred from one trophic level to the next. b in a food web, energy flows and matter is cycled. c each biogeochemical cycle demonstrates the conservation of matter. d the major reserve for nitrogen is in the atmosphere.

Explanation:

The balanced chemical equations in the nitrogen - cycle show that matter is conserved as the number of atoms of each element is the same on both sides of the equations. This is a key aspect of biogeochemical cycles. Option A is about energy transfer in trophic levels, not related to these equations. Option B is about energy flow and matter cycling in a food - web context which is not the focus here. Option D is about the nitrogen reserve in the atmosphere which is not demonstrated by these equations.

Answer:

C. Each biogeochemical cycle demonstrates the conservation of matter.
