Why do leaves change colour?

We all love those incredible reds and yellows in fall...


Now to why.


Plants use carbon dioxide and water to live, they use  photosynthesis to convert that carbon dioxide and water into sugar (glucose to be exact). To help them convert the carbon dioxide into sugar chemical called Chlorophyll comes in and this is why trees leaves are green. This process is called photosynthesis.  When autumn comes the day get shorter, this is how trees know that winter is coming. So they shut off their so called "Food Factories" and the chlorophyll disappears making it orange and yellow. The leaves always had the orange and yellow though in summer the leaves were covered in chlorophyll. In winter trees rest and use the stored energy from summer. Brown can be made from waste in the leaves.

P.S Some trees don't change their leave colours 

Thanks for reading as always and HAPPY NEW YEAR!!!

Are trees that don't change the colours of their leaves called "evergreens"?

Hey, ScienceSquid Here
Your 100% correct! :) Evergreens are the opposite of deciduous which do lose their leaves seasonally.

Thanks for reaching out and I hope I helped! :) (:
