Explanation:
Fuels are usefull because if we didn't have them we wouldn't be able to construct a socialised world and transport.
Starting all the way back from the Stone Age when people made the circle shape, fuels have been used to make energy.
We use wood, to warm ourselfs with fire.
We use fossil fuels to make our veichles work.
Without fuels we would actually die. Food is a fuel and if we didn't have food we would die!
Fossil fuels are bad, not only are they poluting, but causing general climate changes.
We should consider using more solar energy (from the sun's fuel) or wind energy.
For a summary, fuels are important to us as giving us energy and movement to our lives.
The appropriate answer is C. Trees. Trees remove carbon dioxide from the atmosphere through the process of photosynthesis. The carbon dioxide is used along with water and energy from the sun to make food for plants.
Corals extract dissolved carbon dioxide from the ocean to secrete their hard rocky structures.
Crab shells and other marine animals with shells have their bodies incorporated into the seafloor when they die. The sea floor eventually gets subducted where it melts. The carbon present here gets back into the atmosphere via volcanic eruptions.
The number of protons define what element we're dealing with.
