Biogeochemical Cycles Flashcards
Nitrite is converted to Nitrate by this bacteria
Nitrobacter
a build up of nutrients, which can result in algal blooms in water which kill fish
Eutrophication
Order of forms of nitrogen in the nitrogen cycle
Atmospheric nitrogen, Ammonia, Nitrite, Nitrate
Ammonia is converted to this by Nitrosomonas bacteria
Nitrite
4 Places Carbon can be stored in the Carbon Cycle
Atmosphere, Plants, Animals, Ground
21% of the atmosphere is this gas
Oxygen
3 Locations in the Nitrogen cycle
Air, Plants, Roots (nodules)
Can Carbon from the atmosphere or ground go straight to animals?
No
<0.04% of the atmophere is this greenhouse gas
Carbon Dioxide
cycle needed for photosynthetic activities and plant growth
Nitrogen Cycle
Nitrate, Nitrite, and Ammonia are all converted to this by denitrifying bacteria
Atmospheric nitrogen
Atmospheric nitrogen is converted to ammonia by this bacteria
Rhizobium
Nitrite is converted to this by Nitrobacter bacteria
Nitrate
Cycle that plants use for shoot production, flower production, and fruit and seed growth
Phosphorus Cycle
Ecosystems dispose of wastes and replenish nutrients by recycling all elements
2nd Principle of Ecosystem Sustainibility
3 Locations Phosphorus can be stored in the Phosphorus Cycle
Plants, animals, ground
Nitrate, Nitrite, and Ammonia are all converted back to atmospheric nitrogen by this bacteria
Denitrifying bacteria
78% of the atmosphere is this gas
Nitrogen
Where do animals get carbon from in the carbon cycle?
Plants
Cycle that is driven by the production of human fossil fuels
Carbon Cycle
Atmospheric nitrogen is converted to this by Rhizobium bacteria
ammonia
Phosphorus can only travel both ways between these two locations in the cycle
Plants and the ground
Animals can get this form of nitrogen
Nitrate
Ammonia is converted to Nitrite by this bacteria
Nitrosomonas
