NEET BIOLOGY

Detailed explanation-1: -Shelford’s law of tolerance suggests that organisms with a wide tolerance limit for environmental factors show: Narrow distribution with low population. Wide distribution with high population. Wide distribution with high population.

Detailed explanation-2: -Shelford’s Law: A law stating that the abundance or distribution of an organism can be controlled by certain factors (e.g. the climatic, topographic, and biological requirements of plants and animals) where levels of these exceed the maximum or minimum limits of tolerance of that organism.

Detailed explanation-3: -Wide distribution with high population size. The correct answer is – 1. Heliophytes.

Detailed explanation-4: -Organisms have specific requirements for successful growth, development and reproduction. Example: There may be a coldest temperature and hottest temperature an animal can survive in their environment. That is their range of tolerance.

Detailed explanation-5: -abiotic factor, an organism has a range of tolerances within which it can survive. Toward the upper and lower extremes of this tolerance range, that abiotic factor tends to limit the organism’s ability to survive. The wider the tolerance range of a species, the more widely dispersed the organism is likely to be.
