They can make their own food using small inorganic molecules and light energy.
This process is called photosynthesis.Word equation:

How would you test for the importance of light ?
How would you test for the importance of CO2?
how would you test for the importance of chlorophyll?

Hint: Soda lime absorbs CO2
in air.

How could you test the effect of:
Variable light intensities?
Variable CO2 concentrations?
Variable temperatures?

Nitrates: provide the plant with the nitrogen needed to make amino acids and thus proteins.
Magnesium: is needed to make chlorophyll.
Predict how soil with no nitrates /magnesium would affect plant growth.
