Answer:
This is the best explanation for why there is such a small amount of phosphorus that moves into aquatic systems:
1. Phosphorus is highly stable in the atmosphere and remains there for long periods of time.
Explanation:
The phosphorus first cycle is the process by which the phosphate ion passes in very small amounts through the lithosphere from volcanic aeorosols, then to the hydrosphere, where it stays from 20,000 to 100,000 years in the ocean, and finally to biospherere, where rain and erosion helps washing the phosphorus from the rocks into the soil. So, raining is the beginning of the phosphorus´s second cycle, so it is also, the slowest one of the matter cycles that is why the natural total background phosphate levels in several bodies of freshwater range from 0.005 to 0.05 mg/L. Phosphorus remains mostly on land and in rock and soil minerals.
Although abundant on our planet´s sedimentary rock crust and in human body, phosphorus to commercialize is only found in minerals therefore, phosphates mining activity and calcium heating is the only way to get it in its pure elemental form. It is an essential nutrient for plants and animals and a big percentage of the mined phosphorus is used to make fertilizers.

Properties of Bar Graphs
Each bar or column in a bar graph is of equal width. All bars have a common base. The height of the bar corresponds to the value of the data. The distance between each bar is the same.
I believe the correct answer is <span>B. The art and music of this religious group is part of their historic tradition and can even be studied in non-religious or public school classes.
Art can never be separated from history - they are intertwined and almost always studied together. The same thing goes for Eastern Orthodox Christians - they study art and music as part of some of their subjects in school, regardless of the fact that they are considered to be 'religious.'
