What might be the first step of the process????
output answer: You inhale

input question: - Air enters bronchioles - Bronchioles have tiny air sacs called alveoli - Alveoli surrounded by small blood vessels - Oxygen absorbed by small blood vessels - Vessels deliver oxygen to every cell in the body - Blood brings carbon dioxide back to lungs - Carbon dioxide released when you exhale. What might be the first step of the process????
output answer: Air enters the lungs through bronchial tubes

input question: - Over time, more sediment piles on top - The resulting heat and pressure transforms the organic layer into a dark and waxy substance known as kerogen - Left alone, the kerogen molecules eventually crack - The molecules break up into shorter and lighter molecules composed almost solely of carbon and hydrogen atoms - It will turn into either petroleum or natural gas - What might be the first step of the process????
output answer:
Dead organic material accumulates on the bottom of oceans, riverbeds or swamps, mixing with mud and sand
