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

input question: What is the missing first step of the following process:  -  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 - Minerals glue the sediment together into a single rock.???
output answer: Wind or water breaks small pieces off of a rock

input question: What is the missing first step of the following 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 - This makes discovery of the fossil possible.???
output answer: The organism must die to begin the process

input question: What is the missing first step of the following process:  -  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 - Oxygen is released as a by product.???
output answer:
Light energy is absorbed by chlorophyll in a plant
