7. Biotic and Abiotic Factors Biotic components in an environment are directly impacted by the abiotic factors in the ecosystem Biotic components in an environment are directly impacted by the abiotic factors in the ecosystem However, abiotic factors (with the exception of soil) are not impacted by biotic factors However, abiotic factors (with the exception of soil) are not impacted by biotic factors
