Tolerance Range
Tolerance range refers to the range of conditions of the external environment an organism is able to withstand. The population size of a certain species can be lowered if conditions are outside optimum range. The population is lowered because the organisms cannot survive if there is too much or too little of a factor.
It can be expected that animals may have a greater tolerance range than plants because animals have the ability to move to other areas if required. For example, if the temperature was too high for an animal then it would be able to move into a cooler area. A plant does not have the ability to move so therefore plants are able to move their leaves away from the sun however, that may not be as efficient as an animal moving to a cooler area.
