Why are fallen trees important in the ecosystem of the forest?

Fallen trees play a crucial role in forest ecosystems by providing habitat and food for various organisms, including insects, fungi, and small mammals. They contribute to nutrient cycling as they decompose, enriching the soil and promoting plant growth. Additionally, fallen trees create microhabitats, increase biodiversity, and help maintain moisture levels in the forest floor. Overall, they enhance the structural complexity of the ecosystem, supporting a wide range of life.
