Once retinal has absorbed a photon which initiates effects that create nerve impulses, the impulses get carried to the brain, which then processes the impulses along with other signals, ultimately allowing the eyes to see.
As diatoms are made from silica this makes diatomaceous earth very abrasive, and so the sharpness enhances the particles as a pesticide. Diatoms are also useful in forensic studies. If a person has drowned then diatoms are able to enter the human body.

Answer: A scarcity of lemmings will cause for the population of snowy owls to decrease, as their resources have been limited.
The virus introduced to the island in 1982 that reduced the wolf population is an example of a density dependent factor.
In ecology, a density-dependent factor, also known as a regulatory factor, is any force that modifies the size of a population of living creatures in response to population density.
Because of their propensity to maintain population densities, density-dependent factors are also known as regulating factors.
Population size and a density-dependent factor's level of control are correlated, therefore an increase in population will increase the influence of the limitation. Density-dependent factors involve biotic factors such as availability of food , predation, competition, parasitism and disease.
