What are the similarities and differences in the nutrition of bacteria and fungi?

Fungi have a heterotrophic diet. They are not able to independently create organic matter, as plants do. Therefore, they often parasitize trees or are in symbiosis with plants. Some species feed on dead plants and organisms. Therefore, they are essential in nature. Bacteria are also heterotrophic. But there are also cyanobacteria, which are autotrophs. They create glucose on their own during photosynthesis. Some bacteria are parasites. Many species destroy organic matter.
