Question: Explain how petroleum is source of organic compounds?

Petroleum, also known as crude oil, is a complex mixture of hydrocarbons that forms over millions of years from the remains of ancient marine organisms. These organisms, such as plankton and algae, were rich in organic compounds such as lipids, carbohydrates, and proteins. As they died, their remains were buried under sediment and subjected to high pressure and temperature, which transformed them into petroleum. Therefore, petroleum is considered a source of organic compounds because it is derived from the organic matter of ancient organisms.
