These are fun facts about greenhouse gases that...
1.) The three greenhouse gases that are of most concern are Carbon Dioxide (CO2), Nitrous Oxide (N2O), and Methane (CH4).
2.) Greenhouse gases trap heat in the atmosphere warming the Earth’s temperature above freezing. This is known as the Greenhouse effect.
3.) Greenhouse gases are naturally produced; however humans produce additional amounts of certain greenhouse gases.
According to https://umanitoba.ca/faculties/afs/discovery_centre/greenhousegas/media/Fun_Facts_.pdf
Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose.
Starch is stored in the seeds and other plant parts as a food source.
I believe that the answer is frequency. :)
