Nicotinamide adenine dinucleotide (NAD) is known as important cofactor which help in carrying electrons from one reaction to another reaction in the cellular respiration process.
Cells are able to restore performed compounds which are containing a pyrimidine base precursor vitamin for the synthesis of NAD: nicotinamide, nicotinic acid, and nicotinamide riboside.
These elements are taken up from the diet whos containing vitamin B3. Nicotinamide, and nicotinamide riboside both can be absorbed from the gut. Niacin or vitamin B3 also produced within cells with the help of cellular digestion of NAD+.

Answer:
okay so im guessing they want you to compare 2 different land resources. Say a water power station and a coal mine for example.
you could state the different effects the coal mine would have in comparison to the water station.
the coal mine say has pollution produced as a result in producing the energy. Whereas water has a lot better environmental value, but might cost more to produce energy
there is a lot of information of the 2 on google :)
