Question 1

Nitrogen Fixation

Answer 1

When specific microbes use plants as homes and in return, puts ammonium in the soil from nitrogen in the atmosphere.

Question 2

Nitrification

Answer 2

When specific microbes take the ammonium and turns it into nitrates for plants.

Question 3

Denitrification

Answer 3

When specific microbes take the nitrates from nitrification and converts them to nitrogen gas and puts it back into the atmosphere.

Question 4

What are the inputs and outputs of photosynthesis?

Answer 4

Input: Water (H2O), Carbon Dioxide (CO2) (from atmosphere), and Sunlight
Output: Glucose and Oxygen

Question 5

What are the inputs and outputs of cellular respiration?

Answer 5

Inputs: Glucose, Oxygen.
Outputs: Carbon Dioxide (into atmosphere), Water, and ATP (Energy for the cell)

Question 6

What type of organisms can perform photosynthesis and respiration?

Answer 6

All organisms perform cellular respiration. However, only producers can perform photosynthesis.

Question 7

How does BTB work?

Answer 7

BTB works by putting it in water. If the water is acidic, it will turn yellow. If the water is neutral, it will turn green. If the water is basic, it will turn blue. The levels of acidity can be based on the amount of carbon dioxide in the water.

Question 8

How does energy flow differently than carbon?

Answer 8

Energy and carbon usually flow together. However, there are some instances where the energy will be converted to heat and the carbon will be put into the atmosphere (not with the energy).

Question 9

A test tube has a plant in it and is put into the light. BTB is inserted into the water. What color will the water most likely be?

Answer 9

Green as the plant is able to undergo photosynthesis, thus using and losing carbon causing the acidity to be neutral.
