In this video segment, adapted from NOVA, learn how energy from sunlight is transferred through the inhabitants of the reef ecosystem. Photosynthesizing plants and algae convert light energy into chemical energy, which then gets passed through the food web to plant eaters, flesh eaters, and ultimately to scavengers and decomposers.
This video is available in both English and Spanish audio, along with corresponding closed captions.
