Answer 1:
Is when two things exchange gases one gets oxgen the other carbon.
Answer 2:
Er, no. Carbon Exchange is the system whereby different countries exchange carbon credits. For example, co-operating nations may agree that everyone in the world is allowed to use 1 tonne of carbon a year. People from country A actually use 50 tonnes but have lots of money, people from country B use less than .1 and are poor. So B sell their carbon quota to A and everyone is happy for a short while. Then B tries to spend the money and suddenly they are using a tonne of carbon like everyone else but have no credits left to cover it. So country A makes a big speech denouncing B as a polluter while posturing as saviour of the planet even though it's polluting at 50 times the rate of B. Answer 3: Political cynicism aside anwer 2 is in fact correct. It has nothing to do with gas exchange. It is essentially a trading system whereby countries and corporations can buy credits to offset their carbon pollution.
No, as well as the geosphere, the carbon cycle also moves carbon between the atmosphere, the biosphere, and the hydrosphere.
The Oceans
No they can't. They can only obtain carbon dioxide from the leaves through the gas exchange at the stoma (singular: stomata). However, plants can get water, ions, and mineral salts from the soil.
they exchange carbon dioxide and oxygen through the skin(:
I did not quite get this, but if this helps, good. ( this is from my biology book)"Carbon dioxide is made by cells as a waste product of respiration, and is released across the gaseous exchange surface"
The lungs do not exchange oxygen and carbon monoxide. They exchange oxygen and carbon dioxide. They do that in the aveoli.
they exchange in the aveoli and capillaries
Capillaries exchange food, oxygen, and carbon dioxide.
They exchange them through spiracles.

The exchange of oxygen and carbon dioxide
The exchange takes place within the lungs.
It has special skin that allows it to exchange
