Nitrogen Cycle
What is Nitrogen needed for?
- Proteins
- DNA
- Cellular Reproduction
What is Percipitation?
Rainfall, snowfall, etc
where do plants get CO2?
They breathe it in from the atmosphere
what percentage of Nitrogen is in the Atmosphere?
78%
What is Evaporation
When Water turns into gas
how is CO2 returned to the atmosphere
1. Decomposers decompose it after oginisms die
2. through respiration
- fossil fuels
- combustion
- volcanos
- weathering
- shale + limestone
name 2 ways nitrogen gets recycled
1. decomposers
2. a process called denitrification
what creates condensation? and what is condensation?
Clouds, they turn evaporated water back into water that can be precipitated down
how is glucose created
through photosynthesis
4 ways nitrogen gets fixed
Lighting
Soil bacteria
Manure
Nitrifying bacteria that lives on legumes
diffrence between Seepage and Runnoff
Seepage is when water absorbs into the grounds and then accumulates underwater, runnoff is when it runs of into a body of water and accumulates
What happens to orginisms that die underwater
they turn into shale and limestone
what is the diffrence between Nitrites, and Nitrates?
Nitrites create Nitrates (usable nitrogen)
does Transpiration happen through abiotic elements or biotic elements. explain why.
biotic, because its when water thats on leaves evaporates into the air
explain what would happen if there were no decomposers
No decomposers = no oxyegen, with no oxygen, Cellular respiration can not happen, so CO2 will turn into shale and limstones.
and more importantly without decomposers we have no way to recycles CO2 back into the atmosphere, and it would need to be manmade
