Decomposers like worms break down once-living things. Instead of using decomposers to break down hydrocarbons from crude oil, humans use high heat to
A protect the environment.
B improve worker safety.
C speed up the process.
D return nutrients to the earth.
The correct answer is C speed up the process.
High heat is used in the process of refining crude oil to quickly break down hydrocarbons into useful products. This method is much faster than relying on natural decomposers, allowing for quicker processing and production of fuels and other petroleum products.
