In researching how plants live, a student reads about a famous experiment.

In this experiment, a scientist planted a willow tree in a pot of completely dry soil. The scientist let the willow tree grow outside, exposed to sun and rain for 5 years, and did not allow any soil to be added to or taken away from the pot.

The results of the experiment are shown in the table.

The results in the table provide evidence that ______ does not contribute much to the mass of a plant..

• SUNLIGHT

• AIR (or CO2)

• WATER

• NUTRIENTS

• SOIL
