Unit 4.2 Flashcards
What is the definition of Nitrogen fixation?
This is where you take nitrogen from the atmosphere and convert it to Ammonia and Ammonium.
What is the definition of Nitrification?
This is where they take the nitrogen and change it to nitrates and nitrites.
What is the definition of Denitrification?
This is where it can convert the nitrites and nitrates back into a gas that is released in the atmosphere.
What are the inputs of photosynthesis?
Sunlight, CO2 and water
What are the outputs of photosynthesis?
Oxygen and sugar (glucose)
What are the inputs of cellular respiration?
Sugar (glucose) and oxygen
What are the outputs of cellular respiration?
CO2, water and energy/sunlight
What types of organisms perform the process of photosythesis?
Producers
What types of organisms perform the process of cellular respiration?
Producers, consumers, and decomposers.
How do humans affect the carbon cycle?
We add to much carbon by burning fossil fuels which adds to the atmosphere.
How do humans affect the nitrogen cycle?
We affect the nitrogen level by making fertilizer and sometimes putting to much of it into the soil causing a disruption.
How does a PH indicator work?
Basically, in short, the more CO2 there is, the more acidic it will get, and the more acidic it is, the more yellow it will become rather than blue or green.
What is the difference between how energy and how carbon flows through a food chain?
Carbon is never lost in the food chain and always keeps rotating around, while energy is used and not as much is passed on from one level to another.
How will a PH indicator change depending on the organisms?
If there are plants, then there will be photosynthesis, so there will be a source of oxygen, but if there is just animals, then only carbon dioxide is able to be produced.
How will a PH indicator change based on the condition?
If there is light, then plants are able to perform photosynthesis, but if it is dark, they are not able to do that and can only release carbon dioxide.
