4.2 Study guide

Question 1

Nitrogen Fixation

Answer 1

The process of soil microbes taking nitrogen from the air and putting it into the ground.

Question 2

Nitrification

Answer 2

The process of ammonia turning into nitrates and nitrites.

Question 3

Denitrification

Answer 3

The process of soil microbes taking ammonia products and turning it back into nitrogen.

Question 4

Inputs and outputs- Photosynthesis

Answer 4

Inputs- h2o, Sunlight and co2
Outputs- glucose and oxygen

Question 5

Inputs and outputs- Cellular Respiration

Answer 5

Inputs- Glucose and oxygen
Outputs- co2, energy, water

Question 6

What type of organisms perform the processes of photosynthesis and cellular respiration

Answer 6

plants

Question 7

How humans affect the carbon and nitrogen cycles

Answer 7

Humans destroy and farm the soil, so soil microbes can do their nitrogen. They also destroy the environment causing a blockage in flow of carbon.

Question 8

How BTB (a pH indicator) works

Answer 8

The less carbon in the water, means less acidic. the more carbon, the more acidic. BTB shows us the colors that represent this, blue being less carbon and yellow being more carbon.

Question 9

Differentiate between how energy and how carbon flow through a food chain

Answer 9

Carbon can go back and forth between stages. Energy just goes up the chain.

Question 10

Predict how BTB (a pH indicator) will change color in a test tube depending upon:
The contents (plant, animal, both)

Answer 10

Plant- blue (depends on light)
Animal- green
Both- Blue

Question 11

Predict how BTB (a pH indicator) will change color in a test tube depending upon: The condition (light or dark)
