All water on earth, regardless of condition or location is considered a part of this sphere.  

Hydrosphere

100

What reaction will separate elemental carbon from carbon dioxide? 

Photosynthesis

100

The water cycle exists because a certain amount of freshwater is available to living things. What percent of all water on Earth is it?

0.1%

100

Why does matter need to cycle through living things? 

The Law of Conservation

200

What chemical reaction removes carbon from the atmosphere and packages it into living things?

Photosynthesis

200

Which reaction extracts energy from molecules for living cells to use? 

Respiration

200

The three steps for the water cycle are....?

Evaporation - Condensation - Precipitation

200

What are the 2 basic inputs for humans, animals, and decomposers? 

Glucose and Oxygen

300

How can carbon be delivered from the geosphere to the atmosphere?

Volcanic Eruptions or Volcanoes

300

What chemical reaction rearranges the atoms of glucose and oxygen into carbon dioxide, water, and usable energy?

Respiration

300

What are the two most important reasons the carbon cycle exists?

Climate regulation and complex molecules 

300

What are the 3 basic inputs for plants?

Carbon Dioxide, Water, and Sunlight

400

What 2 spheres does nature use as a place to "store" carbon? 

Biosphere and Geosphere

400

Nitrogen fixating bacteria are used in what real world process investigate by our case study?

Water Treatment/Filtration

400

This cycle is responsible for making an element bioavailable for plants to build their chloroplasts. 

Nitrogen Cycle

400

Which life forms use carbon, hydrogen, and oxygen? 

Plants, Animals, Humans, and Decomposers

500

How can carbon move from the hydrosphere into the biosphere?

Shell formation, living things absorb calcium and carbon from the water then use it to form shells. 
500
Bioavailable nitrogen is used to construct this organelle, the location of photosynthesis.  

Chloroplast(s)

500

This blood protein cannot do its job (delivering oxygen to body cells) if there are too many nitrates in your water.  

Hemoglobin

500
Decomposers return a lot of the nitrogen in biomass back to the soil by release what molecule?

Ammonia (NH3)
