Answer:
Survival depends on interaction of many factors, which can vary greatly. For each factor a given species has a range of conditions. If environmental conditions exceed upper or lower limit of tolerance, death can result.
Explanation:
This is the Shelford's law of Tolerance.
This law states that the success of distribution of an organism can be controlled by some factors like topographic, climate, and biological requirements of plants and animals, in which their levels exceed the higher or lower limits of tolerance of the organism.
This was a law proposed by V. E. Shelford in 1911.

Explanation:
Answer: D). Primary species have large numbers of offsprings, and climax communities contain species that have small numbers of offsprings.
An ecological succession is a process of gradual changes occurs in a biological community with respect to changes in the non-living abiotic factors (water, air and sunlight) and with respect to time until the ecosystem attains stability. Primary or pioneer species are the species which invade the previously barren and primitive landmass for their survival. These species make the environment suitable for the growth of other species. These grow and develop in the initial stages of succession. These species are simple organisms which reproduce asexually and produces large number of offsprings. Examples are lichen and moss. Lichen grows on the surface of rocks and acids released by them causes withering of rocks into soil which facilitate the growth of mosses and other plants. Climax community develops in an ecosystem after replacing many previously inhabiting species. Climax community develops in the end of the ecological succession. It contains species which are highly complex and uses sexual reproduction for the production of offsprings which are less in number as compared to those produced by pioneer species by asexual reproduction.
