Calculate the number of acres required to produce 1,000 gallons of oil in one year from microalgae and soybeans. Which one (microalgae or soybeans) requires less space?

microalgae required less space.

Step-by-step explanation:

Amount of oil to be produced = 1,000 gallons

Now,

We know

10,000 gallons of oil is extracted from the miroalgae per acre per year

and,

From soyabeans the oil extracted = 50 gallons per acre per year

therefore,

To produce 1,000 gallons number of acres required by microalgae

= [ Amount of oil to be produced ] : [ oil extracted per acre from microalgae]

= 1,000 : 10,000

= 0.1 acres

similarly

To produce 1,000 gallons number of acres required by soyabeans

= [ Amount of oil to be produced ] : [ oil extracted per acre from soyabeans]

= 1,000 : 50

= 20 acres

hence,

microalgae required less space.
