4.2 S.G. Flashcards
What is Nitrogen fixiation?
Taking Nitrogen from the atmosphere and converting it to Ammonia and Ammonium
What is Nitrification?
Taking Ammonia and Ammonium and converting it to Nitrates and Nitrites
What is Denitrification?
Converting Nitrates and Nitrites to atmospheric nitrogen
What are the inputs and outputs of Photosynthesis?
Carbon dioxide and water are inputs of photosynthesis. Oxygen and sugars are outputs.
What are the inputs and outputs of Cellular Respiration?
What type of organisms perform the processes of photosynthesis and cellular respiration?
Producers do photosynthesis and cellular respiration while Herbivores and Carnivores just do cellular respiration.
How do humans affect the carbon and nitrogen cycles
They affect it by making fertilizer which pollutes areas.
How does BTB work?
At acidic pH, BTB is protonated and the solution appears yellow. At basic pH, BTB is deprotonated and the solution is blue.
What’s the difference between energy and carbon in the carbon cycle.
When carbon has cellular respiration happen, then it goes back into the atmosphere. However, when energy has cellular respiration happen, it gets lost at heat.
