- As the sweat evaporates the sweat sheds molecules into the air - The sweat changes into a gas - Heat is drawn from the sweat - This process draws heat from the body What might be the last step of the process?
Ans: The evaporation also cools the remaining sweat on the body.

- 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?
Ans: Oxygen is released as a by product.

- Gases cause pressure beneath the earth - The gases come to a head and push molten magma to the surface - The magma cools - With enough time the pressure builds up greatly What might be the last step of the process?
Ans: The resulting volcano may explode.

- Carbon dioxide enters the leaves through the stomates by diffusion - Water is transported to the leaves in the xylem - Energy harvested through light reaction is stored by forming ATP - Carbon dioxide and energy from ATP are used to create sugar - Oxygen exits the leaves through the stomata by diffusion What might be the last step of the process?
Ans: The plant reuses the water or the water exits through the stomata as water vapor.
