An example of secondary pollutant is sulfurage
For the answer to the question above, <span>Blurred Vision
A severe headache, visual disturbances such as blurred vision and some epigastric pain that is associated with the development of severe pre-eclampsia or eclampsia. These danger signs and symptoms must be reported immediately as soon as possible. A severe headache and visual disturbances are related to severe vasoconstriction and in a severe increase in blood pressure. Epigastric pain is related to hepatic dysfunction. Ankle edema is a common thing during the third trimester of pregnancy. However, the facial edema is associated with increased fluid retention and the progression from mild to severe pre-eclampsia. Increased energy levels aren't associated with a progression of the client's pre-eclampsia or the development of the complications. In fact, some women are reporting an "energy spurt" before the onset of labor. A mild back-ache is just a common discomfort of pregnancy, unrelated to a progression of the client's pre-eclampsia. It also may be associated with bed rest when the mattress is not firm. Some multi-parous women have reported a mild backache as a sign of impending labor.</span>
<u>Answer</u>: predator and prey
<u>Explanation</u>:
The described graph illustrates the cycle of a predator and prey population. The population curves for predator and prey are not synchronized with each other and their amplitudes differ.
Changes in the prey population will not result in immediate or exactly identical changes in the predator population.
In the attached image, the red line represents the prey population and the blue the predator population. As it can be observed, when the prey population increases in size, the predator population size increases too.
However, this increase is not of the same size and is delayed in time. The predator population will continue to increase even though the prey population has started to decrease.
This has to do with the fact that the adult predators mated and gave birth when the food availability was still high. However, these new young individuals will not survive and reproduce due to decreasing prey. As the prey continues to decrease, more and more predators will perish.
The same cycle will then repeat over and over again.
