When plants use CO2 to make sugar and oxygen
What is photosynthesis?
Where soils can be washed away
What are water basins?
the bacteria that can directly use nitrogen and fix it so that organisms can benefit
What is nitrogen fixing bacteria?
Our atmosphere is 78% what
What is nitrogen gas?
Coal, oil, and natural gases
What is fossil fuels?
Too much phosphorus in water
What is plant overgrowth?
Higher organisms use nitrogen to produce what
What is proteins?
It is an essential nutrient for life
What is phosphorus?
Carbon dioxide + water = sugar + oxygen
What is the equation for photosynthesis?
A source of phosphorus in water other than water basins
What is man-made pollution?
Animal ways decay by the action bacteria create what
Ammonia and nitrate
Natural source for CO2
What is Volcanoes?
when too much CO2 is in the atmosphere
What is the greenhouse effect?
Phosphorus move between soil and plants which are than eaten by animals, the animals use the phosphorus and then their waste products help return the sulfur for the next generation.
What is a phosp cycle?
When animals eat plants containing nitrogen how does it return to the soil
What is animal waste? Or What is plant decay?
nutrient pose supply limits productivity
What is a limiting nutrient?
Animals use oxygen to make more CO2
What is respiration?
Rocks and minerals
Where is phosphorus found?
Can break down the ammonia into the gaseous form of nitrogen
What are denitrification bacteria?
Process in which elements, chemical compounds, and, etc., our past from one organism to another
What is the biogeochemical cycle
