Carbon & Matter
Carbon is part of what molecule in abiotic matter?
Carbon dioxide
Who performs photosynthesis?
Producers
Who performs cellular respiration?
All living organisms
What is mutualism?
Both organisms benefit.
Define ecosystem.
All living and nonliving things interacting in an area.
What is the difference between biotic and abiotic matter?
Biotic is living/dead organisms; abiotic is nonliving parts like air and wate
Where does photosynthesis occur in the cell?
Chloroplast
Where does cellular respiration happen in the cell?
Mitochondria
What is parasitism?
One benefits, one is harmed.
What is an energy storage molecule?
A molecule organisms use to release energy.
If carbon increases in abiotic matter, what must happen in biotic matter?
It decreases.
What two things are needed for photosynthesis to happen?
Sunlight and carbon dioxide (and water)
What gas is released during cellular respiration?
Carbon dioxide
Is predation a type of symbiosis?
No.
Define decomposer.
An organism that gets energy by breaking down dead matter.
Why does the total amount of carbon not change in a closed ecosystem?
Carbon cannot be created or destroyed.
What happens when there is less sunlight?
Producers make fewer energy storage molecules.
How does cellular respiration move carbon?
It moves carbon from biotic matter to abiotic matter.
What happens in competition?
Two organisms compete for the same limited resource.
Define consumer.
An organism that must eat to get energy storage molecules
Explain how carbon moves from abiotic to biotic matter.
Through photosynthesis when producers use carbon dioxide to make glucose.
Explain how photosynthesis affects the amount of carbon dioxide in the air.
It decreases carbon dioxide by using it to make glucose.
Compare photosynthesis and cellular respiration.
Photosynthesis stores energy and moves carbon into biotic matter; cellular respiration releases energy and moves carbon back to abiotic matter.
Explain the difference between mutualism and commensalism.
In mutualism both benefit; in commensalism one benefits and the other is not affected.
Define chloroplast and mitochondrion and explain how they are connected.
Chloroplast is where photosynthesis happens; mitochondrion is where cellular respiration happens. They work together in the carbon cycle.
