Answer:
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.
