Photosynthesis & Cellular Resp.
The process where producers use solar energy to convert CO2 and water into glucose
Photosynthesis
The total amount of energy that enters the ecosystem through photosynthesis.
Gross Primary Productivity
This is also known as the hydrologic cycle.
Water cycle
The sun is the most important part to start this cycle.
Water cycle
The process that breaks down food to make energy for cells.
Cellular Respiration
The amount of energy that remains after ________ is called ________.
Respiration
Net Primary Productivity
When plants release water from their leaves to go into the atmosphere this is called ____________.
Transpiration
Nitrogen from dead animals or excretion from animals is converted into ammonia. The ammonia then can be used as a plant nutrient. What is this called?
Ammonification
What process is this the formula for?
C6H12O6 +6 O2 ——>6 CO2+ 6 H2O
Cellular Respiration
Find the GPP if a wetland has an NPP of 20 kg C/m2/year and a respiration rate of 6 kg C/m2/year.
GPP is 26 kg C/m2/year
Process where bacteria converts atmospheric N2 into ammonia.
Nitrogen Fixation
Carbon is found in the ________ as CO2 and in the _______ as dissolved CO2 gas.
atmosphere, ocean
What is missing from this formula AND what process does this formula show?
6CO2 + 6H2O → C6H12O6 + 6 _____
oxygen & photosynthesis
Increased atmospheric CO2 is an example of a ___________ effect on NPP.
climate change
The conversion of ammonia into _______ and _______. AND what is this process called?
Nitrites, Nitrates, Nitrification

fossil fuels, CO2, climate change
Cellular respiration produces _______, which photosynthesis specifically does not involve.
AND
This type of Respiration is in the presence of oxygen
ATP
Aerobic respiration
Producers only catch about what percent of available solar energy? AND, what is this known as?
1%
GPP
This cycle is the only one that occurs on land AND what process starts the cycle?
Phosphorus Cycle, Weathering
_______ from fertilizers in the _____ and _____ cycles can cause _____ _____, which can be harmful to humans, the environment, and marine animals.
Runoff, N, P, algae blooms
