CED #155
A plot of dissolved oxygen levels versus the distance from a source of pollution.
What are Oxygen Sag Curves?
CED #167
A process in which atmospheric nitrogen is converted into a form of nitrogen that can be available for uptake by plants.
What is Nitrogen Fixation?
CED #48
Provisioning, Regulating, Cultural and Supporting.
What are the four categories of Ecosystem Services?
CED #61
Drip irrigation, flood irrigation, furrow irrigation, and spray irrigation.
What are the Four Forms of Irrigation?
CED #107
An air pollution control device for internal combustion engines that converts pollutants in exhaust into less harmful molecules.
What is a Catalytic Converter?
CED #155
Chemicals that can interfere with the hormones of animals.
What are Endocrine Disruptors?
CED #168
The rate at which solar energy is converted into organic compounds through photosynthesis over a unit of time.
Wat is Primary Productivity?
CED #51
The range of conditions that an organism can endure before death or injury results.
What is Ecological Tolerance?
CED #63
When too much water is left to sit in the soil, inhibiting the plants ability to absorb oxygen through their roots.
What is Waterlogging?
CED #107
An air pollution control device that removes particulates and/or gases from industrial exhaust streams.
What are Wet and Dry Scrubbers?
CED #155
Areas where water covers the soil, either part or all of the time.
What are Wetlands?
CED #169
If there is 100k units of energy in the first trophic level, how many units will there be in the second trophic level?

CED #53
If Island A has a Colonization rate of 5 species per year and an Extinction rate of 2 species per year, calculate the net change in species over a 5-year period.
15 species, (5-2) x 5 = 15 species.
CED #62
Calculate the percent change if in 2020 there were 210 billion emissions of carbon dioxide through cars and in 2025 there were 460 billion emissions of carbon dioxide through cars.
The percent change would be ~119% [(210 - 460/210) x 100].
CED #114
Calculate the percent change of an area if in 2010 it was 39 sound decibels and in 2020 it was 84 sound decibels.
The percent change would be ~115% [(84-39/39) x 100].
CED #157
If a municipal wastewater treatment plant receives influent water that has a nitrate concentration of 45 mg/L, and the effluent water has a nitrate concentration of 9 mg/L. Calculate the percent change?
-80% = [(9-45/45) X 100].
CED #178
