Grass growth is not a chemical reaction but a chemical change because the grass will not go back to its original form after it grows. Like chemical change, a certain object will not go back or reverse it from its original appearance.
Grass growing in a lawn is a physical change because the origonal substance still exists. :) good luck!
A tree growing is a chemical change because the chemical reaction that happens in the trees cells causes the carbon dioxide and water to become sugar (food) for the plant to grow and oxygen it can "exhale" much like we exhale carbon dioxide.
A chemical reaction
The chemical or chemicals formed in a chemical reaction are called the product of the chemical reaction.
Its a chemical reaction.
grass growing is a physical change.
It is a physical change because it is still grass. Nothing new has been made.
Growing of plants involve many chemical reactions.
Mowing is a mechanical process, not a chemical reaction.
Grass growing in a lawn is a physical change because the origonal substance still exists. :) good luck!
It is a biochemical process.
A chemical produced by organic plant's reaction to growing in sunlight.
A tree growing is a chemical change because the chemical reaction that happens in the trees cells causes the carbon dioxide and water to become sugar (food) for the plant to grow and oxygen it can "exhale" much like we exhale carbon dioxide.
creature that feeds on growing grass or herbage?
I would say a little of both. The consistensy of what grass is made of doesn't change,it enlarges, so it could be called a physical change. But to grow, the grass absorbes water and minerals and does photosynthesis, and creates large molecules, so this could be called chemical.
