There would be no food for any of the bugs, because most bugs eat the fungi in the forests. There would be more bugs than there are right now, because certain types of fungi are what kill the bugs. Also it would be to overpopulated even with the trees because fungi is able to kill the trees in the balance of nature.
A forest without trees would be tree graveyard. There would be no life since all trees rely on fungi to aquire water and nutrients. As the trees died of dehydration, there would be nothing to decay them, since fungi are the main organisms to degrade the recalcitrant components of wood (e.g. lignin). Many animals would also die, since they rely on edible mushrooms (most of these would be insects). The few organisms that would survive would be plants that do not associate with fungi, bacteria, and the microbes that hunt bacteria.
it would be nothing!
Thread-like fungi in the forest typically grow within a temperature range of 50-80°F (10-27°C), depending on the species. These fungi thrive in the cool, moist conditions found in forest ecosystems.
Club fungi, like most, like moist dark environments. They can grow on forest floors, or even in a garden.
Trees do not make a forest alone, but with the forest life. Insects, fungi, flowers, birds, squirrels, etc. A forest depends on one and another like these living things depend on others and like how we depend on other people for our daily life.
The forest floor of a rainforest is home to a diverse range of organisms including insects like ants, termites, and beetles, as well as small mammals such as agoutis and armadillos. Decomposers like fungi and bacteria also play a crucial role in breaking down organic matter on the forest floor.
Some plants like mushrooms and fungi can survive without sunlight.
"Would you like to go tree hiking with me in the forest for a day?"
A lot of Plants would suffer and/or die greatly because Fungi provides them nutrients.
The person who was walking in the forest and said, "Gee I wish I could walk without all this stuff in my way. I would like a way to get there without all this stuff."
"Would you like to walk with me on a trail through the lovely forest?"
