Describe the role of fungi in nature. What would become of nature if fungi and bacteria disappeared?

Mushrooms eliminate organic remains of dead plants and animals, decomposing them into the simplest elements and promoting the circulation of substances in nature. Some fungi form mycorrhiza with the root of a higher plant, replacing dead root hairs with trees. Some animals feed on mushrooms. There are parasitic fungi that harm plants. The role of mushrooms is the final stage of the organic compound recycling cycle. In this way, they are similar to bacteria. Without them, life on Earth can stop, which is why they are so needed and there are so many of them everywhere on our planet.
