Which of the following is a disadvantage of using biopower? a. it requires mass production of crops. b. it is readily available in most places. c. it produces net-zero emissions. d. it is biodegradable

A. It requires mass production of crops.

Explanation:

Of all the options the only one that represents a disadvantage is that biopower requires mass production of crops because it could cause loss of biodiversity, degradation of soil quality, soil erosion, food toxicity (due to pesticide residues) and pollution ( use of fossil fuels for agrichemical manufacture, farm machinery and long-distance distribution).

The fact that it is readily available in most places, produces  net-zero emissions and  is biodegradable are all advantages.
