Question

lesson 16: the cycling of matter in ecosystems
how do fungi and bacteria move carbon through the carbon cycle?

Explanation:

Fungi and bacteria act as decomposers. They break down dead organic matter (like plants, animals) containing carbon. Through decomposition, they release carbon - containing compounds (e.g., carbon dioxide via respiration) back into the environment (atmosphere or soil), which is a key part of the carbon cycle. Also, some bacteria (e.g., in the soil) can be involved in processes like carbon fixation or cycling in microbial communities, but the main role in moving carbon in the carbon cycle is decomposition and subsequent release of carbon - based substances.

Answer:

Fungi and bacteria (as decomposers) break down dead organic matter with carbon. During decomposition/respiration, they release carbon - containing compounds (e.g., $\ce{CO_2}$) back into the environment (atmosphere, soil), recycling carbon and moving it through the carbon cycle. Some bacteria also participate in microbial - based carbon cycling processes (e.g., soil carbon cycling).
