TED-Ed: Dead stuff: The secret ingredient in our food chain - John C. Moore

The video explores the origins of food and its connection to detritus, highlighting how all species in an ecosystem are nourished by dead matter. It explains photosynthesis as the process that transforms CO2 and water into glucose, forming the base of food chains. The video contrasts green and brown food chains, emphasizing that most plant matter becomes detritus, which supports ecosystems. It discusses the complexity of food webs, where detritus plays a crucial role, and concludes with nature's recycling system, where waste becomes energy for life on Earth.
