Answer :
Final answer:
Autotrophs use photosynthesis to produce glucose, while heterotrophs engage in cellular respiration to release energy in the form of ATP. The carbon exchange cycle illustrates the interdependence between autotrophs and heterotrophs in the ecosystem.
Explanation:
Cellular Respiration and Photosynthesis
Autotrophs, such as plants, undergo photosynthesis to produce glucose using carbon dioxide, water, and sunlight as reactants. In contrast, heterotrophs, like humans, participate in cellular respiration, breaking down glucose and oxygen to release energy in the form of ATP.
Both autotrophs and heterotrophs are interconnected in the carbon exchange cycle, where autotrophs provide high-energy carbon compounds for heterotrophs, and in return, heterotrophs release carbon dioxide back to autotrophs, highlighting the symbiotic relationship between these groups in the ecosystem.
