The phosphorus at the bottom of the ocean has to somehow make its way back to the surface, to complete the cycle, to begin the cycle all over again.(海底的磷必須找到某種方式回到表面，以完成這個循環，從而重新開始這個循環。)

In a normal water phase, rivers eventually empty into oceans, and once in the oceans, the Phosphorus gets absorbed by water plants like algae.(在正常水相下，河流最終流入海洋，而一旦進入海洋，磷就被藻類等水生植物吸收。)

They mined the rock, artificially break it down and put the Phosphorus into agricultural fertilizers.(他們開采巖石，人工把它分解，然后把磷放進農業肥料里。)

The Phosphorus cycle has been studied a lot by ecologists because like I said, Phosphorus is an important nutrient and it's not so abundant.(生態學家對磷循環進行了大量研究，因為如我所說，磷是一種重要而不充足的營養物質。)

Phosphorus is slowly released as the rocks are broken down and it gets spread around into the soil.(隨著巖石的分解，磷被緩慢地釋放出來，并散布到土壤中。)

Carnivorous plants instead draw nitrogen, phosphorus, and other critical nutrients from their prey in order to build light-harvesting enzymes.(相反，食肉植物從它們的獵物那里吸收氮、磷和其他重要的營養物質，以制造聚光酶。)

Animals end up excreting the phosphorus, which pollutes the ground and water.(動物將此種形式的磷拍到體外，因而污染了土地和水。)

Horse waste is rich in phosphorus and also nitrogen compared to normal soil.(和普通土壤相比，馬糞更富含磷和氮。)

Soil samples from these pens or corrals show ten times the concentration of phosphorus.(來自這些圍欄或畜欄的土壤樣本顯示，磷的濃度是其10倍。)

It can be washed out when it rains or it can be released to the atmosphere, whereas phosphorus combines with calcium and iron, and can be preserved in the soil for thousands of years.(它可以在下雨時被沖刷掉，也可以釋放到大氣中，而磷與鈣和鐵結合，可以在土壤中保存數千年。)
