What causes the vibrant colours of autumn leaves?
A Chlorophyll breakdown
B Extreme snowfall
C Increased rainfall
The breakdown of chlorophyll is a fascinating natural process that plays a pivotal role in the colour transformation of leaves during autumn. The green chlorophyll pigment used in photosynthesis begins to break down as the days grow shorter and the temperature drops. As it deteriorates, it reveals other pigments that were previously masked.
The correct answer is Chlorophyll breakdown.
