Flashcards in Nitrogen Deck (9)
What is the most abundant molecule in the atmosphere
Nitrogen (N2) it is stable and inert. makes up 78%
how can n2 be broken
nitrogen fixation and lightning
what are the primary nutrients for plant growth
two types of fixation
by rhizobia and frankia or phytoplankton in water
Haber Bosch process
what happens when lightning fixes nitrogen
creates nitric acid, which can bond with water molecules in atmosphere and create acid rain
Haber bosch process
for creating a synthetic fertilizer, uses methane gas as a catalyst.
Nutrients enter water (excess nutrients can come from agriculture and urban runoff); then the nutrients cause plants and algae to grow more rapidly. As the plants get thick in the water, light is diminished, causing algae to begin to die lower in the water column. When the algae dies, it is decomposed by bacteria, these bacteria require oxygen from the water. As more of the decomposition occurs because of excess algae growth, oxygen becomes depleted. They is how increased nutrient runoff can cause a hypoxic (low oxygen) or anoxic (no oxygen) state to occur.
impacts of increased nitrogen loading to environmental systems
increased production of food, increase runoff of nitrogen to water bodies-->eutrophication
