Aquatic organisms that lived hundreds of millions of years ago and were buried in silt and sediment resulted in the formation of
a. coal
b. biomass
c. biofuels
d. petroleum

The correct answer is: d. petroleum

The explanation:

petroleum (also known as crude oil or simply oil) is a fossil fuel that was formed from the remains of ancient marine organisms, Millions of years ago, with the compaction by the pressure and high temperature effect forming oil ex: algae and plants lived in shallow seas. .

Petroleum reservoirs can be found beneath land or the ocean floor.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
