Environmental Cycles
Carbon Cycle
-
Respiration
A process in living organisms involving the production of energy, typically wit the intake of oxygen and the release of carbon from the oxidation of complex organic substances.
-
photosynthesis
Process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high energy carbonhydrates such as sugars and starches.
-
Water Cycle
The cycle that processes by which water circulates between the Earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and returns to the atmosphere by evaporation and transpiration.
-
precipitation
rain, snow, sleet , or hail that falls to the ground.

Phosphorous cycle
The Phosphorous cycle is the biochemical process by which phosphorous travels from its source in rocks through different ecosystems to living organisms.
Weathering- weathering of uplifted rocks contributes phosphate to the land. Some phosphates make their way back to the ocean.
Fertilizer- Phosphate fertilizer applied to fields that can runoff directly into streams, become part of a soil pool, or be absorbed by plants.
Excretion and decomposition- Excretion by animals and decomposition of both animals and plants release phosphates on land or in water.
Dissolved Phosphates- Dissolved phosphates precipitate out of the solution and contribute to the ocean sediments.
-
There are 5 steps to the Phosphorous cycle, weathering, fertilizer, excretion and decomposition, dissolved, phosphates, and geologic uplift.
Nitrogen Cycle
The movement of nitrogen between the atmosphere, biosphere, and geosphere in different forms
Nitrogen- a component of proteins and nucleic acids, is essential to life on Earth.
