What are the limiting factors of the ground-air environment?

Humidity in the ground-air environment is the main limiting factor. This is explained by the fact that water plays an important role in the life of organisms. It is a universal solvent, a medium for biochemical reactions in the cell.
Temperature, less often than humidity, manifests itself as a limiting factor. However, at high latitudes, the limiting effect of temperature increases. The vital activity of most organisms is limited by the temperature range from 0 to 40 ° C.
