It is a law stating that a certain organism’s survival and existence depend upon the multifaceted set of conditions wherein each individual has definite minimum, maximum and optimum ecological factors to establish success.
It was develop by American zoologist Victor Ernest Shelford in 1911.
The absence of an organism can be limited by the qualitative or quantitative insufficiency from the various environmental factors which may come up to the limits of tolerance for that organism. Environmental factors involved climatic change, topographic location and biological necessities of both plants and animals.
This law is possibly the more precise indication of natural complexity. Each individual or a population is subject to an ecological change that crop up the minimum and maximum capacity to any complex environmental factors. The range wherein it carried out from the minimum to maximum signify the limit of tolerance of an organisms, if all known factors are actually within the particular range of a certain organisms yet it still fails, it is important to consider extra factors of interrelationships with other organisms
It is been studied that an organisms may have an extensive tolerance for one factor yet a slight array for another. When an organism has a wide range on all factors it indicates that a certain organisms are most widely distributed and are contribute to augment diversity in the community.
