In the darkness, a pinpoint of light becomes visible. Someone has turned on a flashlight. The pin­point grows to the size of the

bulb. Because this is slow motion, only the bulb is bright. Nothing else lights up—yet.
Now the light begins to spread outward from the bulb. It fills a bigger and bigger space. As the light moves forward, it strikes little fog droplets, the ground, a sneaker, a tree, a cat. After each collision, some light bounces off. It is redirected. Some of it reaches a person's eyes. Only then can the light trigger the person's eyes and brain. In slow, stretched-out speech, the person says, "L000000-000000k! Aaaaaaaaaaaa caaaaaa-aaat!"

34kurt

Answer

           The correct option is B.

Explanation

          Ecological succession of any species is composed of following stages:

A. Migration

            The movement of species from one place to another location for the purpose of setting permanently o temporary is known as migration . Forexample

             Siberian crane (<em>Leucogeranus leucogeranus</em>) that live in the arctic tundra of eastern and western Russia. The eastern population of birds migrate to china while western population of these birds migrate to Iran, India and Nepal during winter season.

B. Ecesis

         The complete establishment of species in new habitat that was completely barren or left barren due to some catastrophe is known as Ecesion. This process is dependent upon the climatic, edaphic and biotic factors. The success of plant depend upon some of the adaptations to withstand the unfavorable conditions which includes both biotic and abiotic conditions.

Forexample

               The process of succession in xerosphere start on barren area from pioneer stage covered by crustose lichen, then foliose lichen followed by moss stage, herbaceous stage and a last by shrub stage.

C. Nudation

       The initiation of new species by major environmental disturbance such as volcano eruption is known as Nudation.

D. Reaction

            It represents the effect of established species on the habitat. Forexample plants alter habitat condition as they grow. They extract raw materials from the environment in large amounts and return metabolic wastes. The waste accumulates in large amounts and differ from the original raw materials, thus altering the environment.  

E. Competition

             The phenomenon which involves struggle for existence between two or more individuals growing in same area, that make excessive demand that are similar in nature on the soil is known as competition.

Such struggle may be in between same species or different species. The competition may be interspecific or intraspecific. Because of completion the weak individuals are eliminated as strong ones are retained.
