Q

Phosphorus cycle stages

A

Phosphate in soil -> animals and plants -> decomposition

17
Q

What does phosphate in water turn into

A

Phosphate in water turns into rocks

18
Q

Natural disruption examples

A

Earthquakes volcanoes weather changes in water movement can all affect the cycles above

19
Q

Human disruption examples

A

Poor farming-> not enough nutrients-> use of fertilizers-> run off-> dead zones

Burning of fossil fuels= global warming

20
Q

How does phosphorous pollute water

A

Run off from farms-> dead zones
