Question

which statement does not describe one of the benefits of algae biofuels? algae biofuel production costs are low. algae grows where there is infertile soil and brackish water. algae fixes the atmospheric carbon dioxide that results from burning its biofuel. only 3% of total u.s. cropland is required to grow enough algae to sustain 50% of u.s. transport fuel needs.

Explanation:

Algae biofuel production currently has high costs due to factors like cultivation, harvesting, and processing. The other options describe actual benefits: algae grows in non-arable areas, fixes CO₂ (creating a carbon cycle), and uses minimal cropland relative to energy output. Thus, the statement about low costs is not a benefit.

Answer:

A. Algae biofuel production costs are low.
