Kelly, plants make a chemical reaction powered by sunlight. they take in carbon dioxide from air and react it with water from the ground. The reaction changes them to oxygen and hydrocarbons which are the food we eat. We then do the opposite reaction to get our energy ("sunlight") out from the food!

I was wondering for a science homework, how do we know plants respire? How do we test that they do? I have asked family members and friends, but none of them know how we would confirm they do. Please help!

Hey there,

I know that some college teachers have a problem with students using Wikipedia for citations, but Wikipedia is often helpful to get quick answers to questions like this. Here’s the part of the Wikipedia article on plants that goes into detail about what plants need and why:

http://en.wikipedia.org/wiki/Plants#Structure.2C_growth.2C_and_development

(The short answer is that most plants require nutrients from the soil, including the elements nitrogen and phosphorous.)

I am doing my AP Biology homework and i was required to find out what plants use as food. I am aware that they use Carbon Dioxide for food but soil was something that caught me. Do plants really use nitrogen as food? How does it help them? Can anyone be more clear and go in depth about this? Thanks!
