    you will learn about photosynthesis in intro bio, AP/IB bio, freshman in college bio, and probably more classes including anything about plants or sometimes cell bio classes too

    This video is good, but it perpetuates the misconception that photosynthesis exists to make food for animals. In fact, it is to make food for the organism that is undergoing photosynthesis. Something may or may not eat it.
