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.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
