Fungi often function as decomposers in an ecosystem. If you traced the carbon in a molecule of carbon dioxide from the air into
a molecule of glucose inside a fungal cell, what other organisms did it have to go through (if any) to get into the fungus?a. Fungi can take up carbon dioxide from the atmosphereb. Autotroph AND a primary consumerc. Non-photosynthetic bacteriad. A primary consumere. A secondary or tertiary consumerf. Plant or other autotrophic organism
Fungi are the decomposers. Hence, they decompose the tertiary species into raw mineral and nutrients which later on get mixed with soil and air.
Now, in the cyclical food chain after the decomposers autotrophs come which shall absorbs the above mentioned nutrients and raw mineral from soil. Once these nutrients enter into the body of plants or autotrophs, they are further passed on to primary consumers, secondary and tertiary consumers.
I think the correct answer would be D. In the process of petrification, a tree burning is not included. Petrification is a process that involves organic materials turning into fossils by replacing the original contents of a certain object with minerals.
