The following is the correct order of the whole phosphorus cycle:
1. Erosion and weathering of the rock deposits the phosphorus into water.
2. Aquatic plants absorb and assimilate the dissolved phosphate.
3. A fish consumes aquatic plants.
4. The fish is caught and consumed by a bear.
5. The bear, after a fruitful life, dies from an old age.
6. Decomposition of the dead bear discharged phosphorus into the soil.
7. The soil washes into a lake, where it sinks to the bottom to turn into a sedimentary rock.
