If the walls of the biodome are made of a material that absorbs and locks away carbon dioxide from the air, we can predict that the concentration of carbon dioxide in the air inside the biodome will gradually decrease over time. This is because the carbon dioxide molecules will be absorbed and locked away by the walls, making them unavailable for the plants and animals to use.
If the concentration of carbon dioxide in the air inside the biodome decreases significantly, it could have several effects on the living things inside. Plants rely on carbon dioxide for photosynthesis, which is the process by which they produce energy and oxygen. If the concentration of carbon dioxide in the air is too low, it could limit the ability of the plants to produce energy and oxygen, which could ultimately affect the survival of the animals in the biodome.
In addition, if the concentration of carbon dioxide in the air inside the biodome is significantly lower than the concentration of carbon dioxide in the outside environment, it could create a gradient that could cause carbon dioxide to diffuse into the biodome over time. This could affect the long-term sustainability of the biodome and would need to be carefully monitored and managed by the engineers.
Overall, the absorption of carbon dioxide by the walls of the biodome could have significant effects on the living things inside, and it is important for the engineers to carefully consider and manage the carbon dioxide levels to ensure the long-term sustainability of the biodome.
