Why are lichen and moss on the forest floor od a deciduous forest?

Lichen and moss thrive on the forest floor of deciduous forests due to their ability to tolerate shade and retain moisture, which is abundant in these environments. They play a crucial role in the ecosystem by aiding in soil formation, preventing erosion, and providing habitat for small organisms. Additionally, their presence indicates a healthy, balanced ecosystem, as they are sensitive to air quality and environmental changes. Their resilience allows them to colonize nutrient-poor substrates, contributing to biodiversity in the forest.
