There are many abiotic factors present in the temperate deciduous forest, but some of the most common are rocks, climate, soil, sunlight, rain and temperature. The abiotic factors of an ecosystem are all the nonliving things that affect the survival and reproduction of living organisms.
All of the living and nonliving parts of an ecosystem have an effect on each other. In the temperate deciduous forest, the amount of sunlight available affects plant growth. If plants do not receive enough sunlight, they will die off or fail to thrive, leaving less food available for the animals in the ecosystem.
The climate of the temperate deciduous forest is another important abiotic factor affecting living organisms. Plant growth and animal survival are both affected when an ecosystem's temperature is too high or too low. Soil pH, water quality and the amount of rainfall the temperate deciduous forest receives also affect the survival and reproduction of plants and animals.
