Nitrogen Cycle 1
What is the definition of the word reservoir?
What is a place where anything is stored
What is Biological Fixation?
Free living bacteria-highly specialized bacteria live in the soil and combine N2 with H2, bacteria fixes 30% if avaiable N2. Produces ammonium (NH4) where most nitrogen fixing happens.
What is lighting?
What is the natural occurrence of electrical discharge.
What are the reservoirs for nitrogen?
What is Plants, Animals, Bacteria, Atmosphere, and Soil.
What the definition of process?
What is nitrification?
What is the Negative consequences of excess Nitrogen?
What is smog components, nitric oxide, nitrous oxide, acid rain, and allows non-native plants into an ecosystem.
What are the forms of nitrogen found in the Nitrogen cycle?
What is Nitrogen compounds, Nitrogen must be converted to more chemically available forms for plants and animals to use.
What is Nitrogen Fixation?
What is a process where N2 molecules in the air break apart and combine with other atoms to form ammonium or NH2. Nitrogen gets fixed when it combines with Oxygen to Hydrogen.
What is assimilation?
What is human impact?
What is cause use of synthetic (man made) nitrogen fertilizers. Effect Fixes more nitrogen than all natural sources combined.
What is Nitrogen?
What is makes up about 78% of the atmosphere, Nitrogen gas is colorless, odorless, and generally intent or unreeactive. Most organisms can´t use vital components of food, fertilizers, and explosives.
What is the definition of Atmospheric Fixation?
What is Energy from lighting breaks N2 molecules apart, N2 atoms combine with oxygen forming nitrogen oxides. N2O dissolves in rain forming Nitrates NO3. Nitrates get carried to the ground by Rain.
What is ammonification?
What is part of the decay process. When a plant dies or leaves waste products, decoomposers like fungi sf bacteria turn N2 back into ammonia, ammonia is absorbed and stored in the soil.
What is the nitrogen cycle?
What is, Describes how nitrogen N2 moves between various reservoirs.
What are the processes of the Nitrogen Cycle?
What is Fixation, Assimilation, Ammonification, Denitrification.
What is the definition of Industrial Fixation?
What is under certain conditions industrial plants combine with nitrogen and Hydrogen forming NH3. Ammonia is used has fertilizer.
What is bacteria?
What is small organisms found all over Earth
What can Nitrogen be used for?
What is food, fertilizers, and Explosives
What is Denitrification?
Converts nitrates NO3 in the soil to N2 sediments. Denirifying bacteria that live deep swampy sediments where O2 is not easily accessible. These bacteria take O2 from nitrates leaving the byproducts nitrogen gas N2.
