The movement of water from a body of water to the atmosphere.
What is evaporation?
One human activity that contributes nitrogen and to the land and often pollutes waterways.
What is the use of fertilizers?
OR
What is the burning of fossil fuels?
The difference between how matter and energy flow through the environment.
What is matter is recycled and energy flows in one direction from producers to consumers?
The organisms that form as the keystone of the Nitrogen cycle.
What are bacteria (bonus points for fungi)?
The way most animals acquire their Carbon and Nitrogen.
What is consuming food.
The carbon-based molecule produced by plants.
What is glucose?
The process that some bacteria use to convert nitrogen gas from the atmosphere into a useable form of ammonia.
What is nitrogen fixation?
Three possible solutions to increase oxygen content in an ecosystem.
What are increasing the number of producers, increasing light for photosynthesis, and decreasing the number of consumers?
These living things perform cellular respiration to convert glucose into usable energy.
What are ALL living things (including plants)!
The most abundant element in the earth's atmosphere.
What is nitrogen?
Three ways to decrease Nitrogen-based waste in an ecosystem.
What are increase bacterial activity, remove consumers, increase number of producers, decrease decaying organic matter.
The process by which plants take in atmospheric carbon and release atmospheric oxygen.
What is photosynthesis?
The formula for cellular respiration.
What is C6H12O6 + 6O2 --> 6CO2 + 6 H2O + Energy?
The process that some bacteria use to convert useable nitrates back into unusable nitrogen gas.
What is denitrification?
The primary cause of nutrient (carbon, nitrogen, oxygen, water) imbalance in nature.
What is human activity?
The process by which all living things take in atmospheric oxygen, releasing atmospheric carbon dioxide and usable energy in the process.
What is cellular respiration.
