4.2 Flashcards
What is nitrogen fixation?
the process where nitrogen, which is in the ground, goes to proteins which turn it into ammonium
what is Nitrofictation?
The process where the ammonium turns into nitrates through the nitrifying proteins.
what is Denitrofication?
The process where the Nitrates are turned back into nitrogen and they return into the atmosphere.
what goes into cellular respiration and what comes out?
Goes in: Oxygen and glucose
Comes out: energy, CO2, and H20.
How do humans affect the nitrogen cycle?
Humans use nitrogen to grow crops better. If this leaks into a river or reservoir, then it can lead to excess algae growth, which can damage or hurt the ecosystem in the water.
What are some differences between the energy and the carbon in the carbon cycle?
The carbon will start the cycle again once it is finished, while the energy will leave the cycle as heat. One similarity is that they both originate from the producers.
What steps must you go through to have carbon in a decomposer?
Atmosphere to producer to soil to decomposer
Why is it so rare to see carbon in carnivores?
Because there is a long list of steps that the carbon has to go through and most carbon atoms don’t make it that far.
