Question

1. what do fungi and bacteria do in the carbon cycle?

Explanation:

Fungi and bacteria are decomposers. Decomposition releases carbon. Some bacteria can also fix carbon.

Answer:

Fungi and bacteria play crucial roles in the carbon cycle. Fungi break down complex organic matter (such as dead plants and animals) through decomposition, releasing carbon back into the environment as carbon - dioxide during respiration. Bacteria also participate in decomposition. Some bacteria can perform photosynthesis (like cyanobacteria) and fix carbon from the atmosphere into organic compounds, while others break down organic matter and release carbon.
