What are non living factors in a forest under story?

Non-living factors in a forest understory include elements such as soil composition, moisture levels, light availability, temperature, and humidity. These abiotic components significantly influence the types of plants and animals that can thrive in this layer of the forest. Additionally, factors like nutrient availability and pH levels in the soil affect growth and biodiversity in the understory ecosystem. Together, these elements create the conditions necessary for supporting life in this unique environment.
