Which of the Following is an Important Role for Fungi

Question

Which of the following is an important role for fungi in the carbon cycle?
A) One of fungi's main roles is to provide already fixed carbon to plants that the plants then use for the production of cellular tissues.
B) Fungi get involved in the fixation of carbon by undergoing photosynthesis.
C) Fungi help release fixed carbon back to the environment for other plants and photosynthetic organisms to utilize.
D) All of the above are important roles for fungi.

Accepted Answer

Fungi play an important role in the carbon cycle by breaking down organic matter and releasing fixed carbon back into the environment for other organisms to use. They do not undergo photosynthesis, and while they may provide already fixed carbon to plants, this is not their main role in the carbon cycle. Therefore, option C is the best choice.
