    Is this interpretation that, you are looking for:

    "Why Leaves Turn Color in the Fall” tries to describe why leaves turn color in fall but fails because her thesis is unable to concentrate on certain ideas an ends up a fact instead of a argument. She neglects to keep her reader focused on her objective and makes the entire essay just boring. This is undoubtedly false because she clearly states in the beginning of how chlorophyll is used to produce a rich green color which leads to photosynthesis. She finishes by saying " Sometimes one finds in fossils stones the imprint of a leaf, long since disintegrated, whose outlines remind us how detailed, vibrant, and alive are the things of this earth that perish”(323). What’s disappointing is Ackerman discusses the process of how then and the next thing you know she is debating about life and death. Thanks to Process Analysis usually arranges a series of events in order and relates them to one another, as narration and cause and effect, except process analysis explains how it happens instead of what happened.

    Leaves contain chlorophyll,xanthephyll and carotene.

    As the sap goes lower in the tree's roots,chlorophyll is purged from the leaves and in some trees xanthophyll predominates leaving a bright yellow color,some show bright orange.

    As these chemicals disappear the leaves turn brown and fall.
