Part I
In extension to measuring the amount of light that enters the eye, the pupillary light reflex presents a helpful diagnostic tool. It provides for examining the uprightness of the sensory and motor functions of the eye. if your pupils didn't shut suddenly when abruptly disclosed to light, you'll get a tremendous shot of light (simultaneously with UV rays and other possibly dangerous rays) to your retina, which can severely mess up your vision.
Part II
Without it, we would go blind. If there is not sufficient light and the pupils do not dilate, a small number of light will pass to the retina and the image will be damaged.
The correct answer is D.) Second Sucession.
b. biotic
Organisms within an ecosystem are biotic factors in that ecosystem. Thus, option B is correct.
The term biotic factors has been defined as living factors present in the ecosystem. Biome is a separate biogeographical region that contains its own living and non-living factors along with a characteristic climate. The examples of biomes are: Tundra, Temperate, Desert, etc.
Changing a biotic or abiotic factor can affect each other or even the entire biome because these factor live in a state of dynamic equilibrium by being interdependent on each other. Therefore, if this equilibrium is disturbed then the survival of some living organism may be disturbed that can eventually lead to ecological succession.
The nitrogen cycle is a biogeochemical succession process of nitrogen that involves: fixation, ammonification, nitrification, and denitrification. Like any other biogeochemical cycles. This process undergoes and affects the biological, geometrical and chemical aspects in the ecosystem and the abiotic and biotic community.
Therefore, Organisms within an ecosystem are biotic factors in that ecosystem. Thus, option B is correct.
