Symbiotic Relationships and Carbon Cycle

In this video, Ed Chapman discusses nutrient cycling and organism interactions in ecosystems, focusing on the carbon cycle. He explains how carbon moves through the ecosystem via photosynthesis and cellular respiration, and how fossil fuels impact carbon storage. The video also covers symbiotic relationships, including mutualism, parasitism, and commensalism, with examples like ants and ant trees, ticks and dogs, and cattle egrets and cows.
