Presentation on theme: "Biogeochemical Cycles Defined: Movement of water through the atmosphere 75% of the earth is water 99% of water undrinkable (salty & frozen) Water recycles."— Presentation transcript:
Animals – Ingest P when plants eaten – P continues to move up food chain P
Phosphorus (P) Cycle Decomposers – Breakdown dead matter and release P into soil P P
Phosphorus (P) Cycle Human Contribution – Adding excess P from fertilizers – P washes into lakes, etc… – Excess P causes extreme algae growth P P PP P P
Kobe Kuiz 1)Name and define the 6 stages of the water cycle. 2)How is oxygen released into the atmosphere? 3)In which cellular process is oxygen removed and used from the atmosphere? 4)Which organic molecule is created by photosynthesis? 5)In which cellular process is carbon dioxide released into the atmosphere? 6)How are humans disrupting the carbon cycle? 7)How does nitrogen fixation and nitrification differ? 8)How do plants obtain nitrogen? 9)Which objects release phosphorus over time? 10)How are humans disrupting the phosphorus cycle?
