Cycles
Water Cycle
-
-
-
-
When water molecules clouds collect into big enough drops,they fall on us as rain, snow, sleet, or hail depending on the temperature.
-
Water returns to the earth through precipitation also known as rain, snow, sleet,or hail.
There is always certain amount of water vapor in the atmosphere, it comes from the surface water.
-
-
This ground water feeds wetlands,lakes, and streams.
Carbon Cycle
-
-
-
-
Rocks and soil; dissolved in seawater, inside the earth's mantle; and in the air, as carbon dioxide and that's the Carbon Cycle.

Nitrogen Cycle
-
-
-
Nitrogen from the atmosphere falls to the ground, thanks to precipitation.
Nitrogen is a key component of the bodies of living organisms. Nitrogen atoms are found in all proteins and DNA
Different type of of bacteria grabs onto ammonia molecule and combines it with oxygen called nitrification
-
Phosphorous Cycle
-
When nitrogen and phosphorous from fertilizer are carried in runoff to lakes and oceans, they can cause eutrophication, the overgrowth of algae.
Phosphate compounds in the soil can be taken up by plants and, from there, transferred to animals that eat the plants.
Phosphorous is often the limiting nutrient, or nutrient that is most scarce and thus limits growth, in aquatic ecosystems.
When phosphorous-containing compounds from the bodies or wastes of marine organisms sink to the floor of the ocean, they form new sedimentary layers.
-
Phosphorus is an essential nutrient found in the macro molecules of humans and other organisms, including DNA.
