Cutting down a tree. shredding of paper as well as same of the irreversible change
No. Trees' leaves change colors beacuase when winter comes around, they will not have the energy to keep leaves, so they seal off the leaves from the rest of the tree. When the leaves are cut off from the rest of the tree, the chlorophyll in them dies, and turns brown.
Because any chemical changes occur.
The act of cutting the tree is a physical change. However, there are chemical changes that take place as a result of cutting the tree. All plants have an ability to "feel" when they are being damaged and the plant cells around the damaged ones stiffen to attempt to prevent further damage.
no it is a physical change the tree did not change into a different thing it simply changed in size
chemical change..... we just talked about this in science today and that is what my teacher said

it is a physical change because its chemical composition does not change and no new substance is formed

Breaking of a tree branch is a physical change because the chemical composition of the wood remains the same before and after the branch breaks. Only the physical appearance and state of the branch changes.
Burning wood is an example of a chemical change because the wood reacts with oxygen to release energy in the form of heat and light. The other examples are physical changes: cutting paper, mashing potatoes, chopping down a tree, and mixing paint involve changes in shape, size, or state without altering the chemical composition of the substances involved.

no ... physical
Yes, when you cut down a tree and it decomposes or is burned, the carbon stored in the tree is released back into the atmosphere as carbon dioxide. This contributes to the increase of carbon dioxide levels in the atmosphere, a greenhouse gas that contributes to climate change.
