Phosphorous cycle | Ecology | Khan Academy 

cant believe you still have time to do them Sal! inspiring!

Very illuminating for someone who has know idea what phosphorous cycle is

Very understandable video Sir. I am from India and I had a request that if you would also make a video on the Sulphur cycle , it would be really nice.

Great video Sal you always explain things so well.

It's importance to forming cell walls (phospholipids) is worth mentioning.

Great video once again.

I just got stuck watching this because we have a quiz bee tomorrow in Environmental Science and our coverage is part Phosphorus Cycle
