What will happen to a forest of the sun was blocked for a year?

If the sun were blocked for a year, a forest would undergo severe stress due to the lack of sunlight necessary for photosynthesis. Most trees and plants would struggle to survive, leading to widespread die-off and a collapse of the ecosystem. The temperature would drop significantly, potentially causing frost and further harming vegetation. Ultimately, the forest could transform into a barren landscape, significantly altering the habitat for wildlife.
