I know plants take in carbon dioxide and give off oxygen. How does this work as a cycle in a terrarium which is airtight?
I understand that the plant can take in water through the roots, release it from the leaves, and that evaporation and condensation and even precipitation can take place in a terrarium.
So the water cycle makes sense to me, but how is the air recycled?
