What is the role of CO2 in the atmosphere?
It used in carbon cycle.
What gas is fixed by the plant during Calvin cycle?
carbon dioxide is used in the Calvin cycle.
A reactant used in the Calvin cycle is?
Carbon dioxide (CO2).
Carbon is used to make sugars in which step of the carbon cycle?
photosynthesis(:
Where does the carbon dioxde used by plants come from?
Humans inhale oxygen, and breath out carbon dioxide. It is like a cycle.
What is the continuous movement of carbon from nonliving environment into living things and then back to nonliving?
the carbon cycle
Why is the carbon cycle used again and again?
Because it wouldn't be a cycle if it didn't get used again and again?
What is the role of CO2 in the atmosphere?
It used in carbon cycle.
What is alternative fossil fuels?
Fossil fuels come from fossilied plant matter in the ground. Alternative fuels are alternatives to fossil fuels, and these are mainly carbon fuels that take their carbon from carbon dioxide in the atmosphere (as fossil fuels do) but on a carbon cycle with a much shorter term. An example is wood, which can be burned as more trees are growing and absorbing carbon dioxide.
Why is bio-diesel considered an alternative fuel?
Bio-diesel is not a fossil fuel, rather it is manufactured from vegetation and algae, so any carbon dioxide it emits when burnt is part of the carbon cycle and does not add to global warming.This is why it is an alternative to fossil fuels.
What gas is fixed by the plant during Calvin cycle?
carbon dioxide is used in the Calvin cycle.
A reactant used in the Calvin cycle is?
Carbon dioxide (CO2).
Carbon is used to make sugars in which step of the carbon cycle?
photosynthesis(:
What cycle involves photosynthesis and respiration?
No cycle. Transpiration is part of the water cycle, and photosynthesis is what plants do to feed themselves.Carbon cycle involves both of them. Photosynthesis remove Carbon from atmosphere. Respiration release them back
What are the nature cycles?
nitrogen cycle, carbon cycle, water cycle, and sulfur cycle
Is carbon dioxide the only product of the Krebs cycle that is not reused or used in other stages of cellular respiration?
Yes, carbon dioxide is the only product of the Krebs cycle that is not reused or used in other stages of cellular respiration.
What is carbon cycle?
it is a cycle in which carbon is constantly renewed
