input question: -  A person takes in oxygen through their nose or mouth - The oxygen travels into the body - Breaks down into glucose - Carbon dioxide is produced by the glucose breakdown  What might be the last step of the process????
output answer: The carbon dioxide is exhaled out of the body through the nose or mouth.

input question: -  Wind or water breaks small pieces off of a rock - The wind or water deposits tiny rocks - The rocks become known as sediment - The layers of sediment are pressed together by other layers of sediment on top - Minerals from the rocks in the sediment dissolve  What might be the last step of the process????
output answer: Minerals glue the sediment together into a single rock.

input question: -  The organism must die to begin the process - The soft tissue decomposes - The bones are left behind - Scavengers tear the body apart and move the bones elsewhere - Wind and rain also scatter the bones further - The bones left behind will weather and become buried by sand and soil - The proteins in the bone are replaced with minerals that are dissolved in the soil - This creates a rock-like substance called a fossil - Water and wind erosion wear away the layers of soil on top of the fossil  What might be the last step of the process????
output answer: This makes discovery of the fossil possible.

input question: -  Light energy is absorbed by chlorophyll in a plant - The light energy is used to convert carbon dioxide - The plant uses nutrients in the soil - The plant uses carbon dioxide in the air to produce glucose - The plant uses the glucose to give itself energy  What might be the last step of the process????
output answer:
Oxygen is released as a by product.
