Final answer:
Abiotic factors that have lower values in a forest ecosystem at a higher altitude include humidity, light intensity, and temperature.
Step-by-step explanation:
The abiotic factors that might have lower values in a forest ecosystem at a higher altitude compared to a forest ecosystem at a lower altitude are humidity, light intensity, and temperature.
Humidity: As altitude increases, the air becomes cooler and moisture condenses, resulting in lower humidity levels.
Light intensity: The higher the altitude, the greater the absorption and scattering of sunlight by the atmosphere, which diminishes the amount of light reaching the forest floor.
Temperature: Higher altitudes are characterized by lower temperatures due to decreased air pressure and thinner atmosphere.
