Environmental factors are all those biotic (living) and abiotic (non-living) factors that can influence living beings. For example, availability of prey, presence of predators, number of daylight hours per day, humidity conditions, temperature regime, etc.
Not all environmental factors influence an organism in the same way .
For example, if we consider a living being such as the beet plant, we can say that it is tolerant to salinity, that is, it will be able to continue growing if the amount of salt in the soil increases. However, the beet plant will not withstand an increase in the amount of water around its roots. In other words, it tolerates an increase in one environmental factor (salinity), but not in another (amount of water).
