100
All organisms require nitrogen to make amino acids which are used to build these.
What are proteins?
100

Producers (plants) obtain carbon dioxide from this "sphere"  _________ during photosynthesis.

What is the atmosphere?

100
The chemical formula for ammonia.
What is NH3?
100

The gas produced during animal respiration.

What is CO2 (carbon dioxide)?

200
Water enters the atmosphere as this.
What is water vapor?
200
Nitrogen gas makes up this percentage of Earth's atmosphere.
What is 78 percent?
200

This is the largest carbon reservoir on the planet Earth.

What is the ocean?

200
The chemical formula for atmospheric nitrogen (free nitrogen).
What is N2?
200
This rock/stone includes a high concentration of carbon.
What is limestone?
300
The process by which water changes from liquid form to an atmospheric gas.
What is evaporation?
300

This occurs when an overabundance of nitrogen has leached into a body of water from fertilizer or animal manure on farms. 

What is Eutrophication

300
Consumers obtain carbon in the form of _____________ by eating producers.
What is carbohydrates, lipids (fats), or starch/sugar?
300
The process where the composition of organic matter is broken down into simpler parts.
What is decomposition?
300

Global temperature does this as more carbon dioxide is released in the ocean and atmosphere.

What is increases?

400
Water vapor becomes tiny droplets that form clouds.
What is condensation?
400
The conversion of nitrogen gas (free nitrogen) into ammonia is this process.
What is nitrogen fixation?
400
Carbon is found in this form in the ocean, especially in seashells.
What is calcium carbonate?
400

This particular type of vegetable that hosts nitrogen fixing bacteria, and are especially good crops in replenishing the soil.

What are legumes?

400
The process in which fossil fuels are burned.
What is combustion?
500
When water droplets that form clouds are large enough, the water returns to Earth's surface in this form.
What is precipitation?
500

Soil bacteria convert nitrates into nitrogen gas which returns to the atmosphere in this process.

What is denitrification?

500

This process is responsible for the largest amounts of carbon being released into the atmosphere from human activity. 

What is burning fossil fuels?

500
Farmers add this to their fields in order to produce more fixed nitrogen (ammonium) in the soil.
What is fertilizer?
500
