Photosynthesis
Alternative name for photosynthesis
Carbon assimilation
How do plants store carbon?
As biomass (cellulose, lipids, proteins, etc...)
What is the name of the stage when atmospheric nitrogen is converted into NH3 or NH4+.
Nitrogen fixation
What is it called when animals are converted into phosphate ions (PO4-)?
Decomposition
What is it called when nitrates are absorbed by plants?
Assimilation
What part of a plant takes in carbon dioxide?
Stomata
What is the name of the cellular process plants undergo to release carbon into the environment?
Cellular respiration.
What is produced by ammonification.
NH4+
Define leaching?
Phosphate ions in the soil diffuse to bodies of water.
What is the chemical formula for atmospheric nitrogen?
N2
Equation for photosynthesis
6CO2 + 6H2O + light energy -> C6H12O6 + 6O2
Give the equation of the process plants undergo to release carbon dioxide into the atmosphere.
C6H12O6 + 6O2 -> 6CO2 + 6H2O + energy
What is the name of the process when bacteria convert NH4+ into NO2-?
Nitrification
What stage explains when phosphate is absorbed by plants?
Assimilation
True or False: Both aerobic and anaerobic bacteria are decomposers in the process of ammonification?
True
What is the rule of 10% (second law of thermodynamics)?
Only 10% of energy stored in plant biomass is transferred to the next trophic level.
How does carbon enter the lithosphere?
Decomposers (bacteria/fungi) break down organic materials (dead plants/animals)
Lightning
Why is phosphorus important to plants?
It makes up DNA
What is the chemical formula of ammonium?
NH4+
What does NPP = GPP - R mean?
NPP = Net primary productivity
GPP = Gross primary productivity
R = respiration
How can pressure turn plants into carbon sources?
Heat and anaerobic compression turns plants into coal
What is the process called when nitrates (NO3-) is converted back into atmospheric nitrogen?
Denitrification
How does algae add to the phosphorus cycle?
When algae dies and gets decomposed, the phosphorus gets released back to the environment.
What do plants do with the nitrogen they absorb?
Build organic molecules like proteins, amino acids, DNA, etc...
