As we know, biomass energy is the energy that is generated by a living organism or by the processing of them. In the present case, it is referring t the second case (processing of living organisms) mostly focused on plant-based energy. Therefore having this in mind we can proceed to analyze the following sentences
A.- Organisms can regenerate and renovate so this doesn't suppose a disadvantage.
B.- This must be approached carefully, it depends on the source, but in crop farming, we could say that it is correct, so it wouldn't imply a disadvantage.
C.- This is a highlight that crops have, as well as cattle, often require large amounts of terrain and overexploit soil to cover demand, so this is a disadvantage.
D.- This is mostly true, as is organic matter it will wilt and disintegrate leaving few residues.
