What is nitrate (NO3-)?
200
The only way humans can obtain phosphorus is by this method.
What is mining?
200
Humans have been adding CO2 in the atmosphere at a rate faster than natural systems remove it through this process.
What is the combustion of fossil fuels?

What is nitrification?
300
When excess phosphorus enters waterways it can stimulate a sudden and rapid growth of algae called an ______ ________.
What is an algal bloom?
300
CO2 dissolved into the ocean is taken up by photosynthetic organisms and sedimentation. This process releases he CO2 back into the ocean and atmosphere.
What is respiration?
300
We can represent the distribution of biomass, numbers, or energy among trophic levels with this.
What is a trophic pyramid?
400
Location of Sublimation
What is C?
400
The process where excess nitrogen runoff into aquatic ecosystems creates an excess of algal growth followed by an increase in decomposition activity which depletes the oxygen in the water.
What is eutrophication?
400
Unlike nitrogen, phosphorus rarely changes forms and is most commonly found in this form.
What is phosphate (PO43-)?
400
This is an abiotic source of carbon in the atmosphere.
What is volcanic activity?
400
If gross primary productivity in a wetland is 20,000 kcal/m2/year and respiration is 12,000 kcal/m2/year, the net primary productivity of the wetland is_______.
What is 8,000 kcal/m2/year.

What is assimilation, mineralization, sedimentation, geologic uplift, and weathering?
500
The greatest impact of extra atmospheric CO2.
What is climate change?
500
These are 2 reasons why not all energy is transferred from one trophic level to another.
What is not all energy is usable (digestible) and some energy is used by the organism (moving, eating, maintaining body temp)?
