There may be too many plants present or too few animals in the biodome hence the decrease in carbon dioxide .
<h3>What is a biodome?</h3>
The term biodome refers to an artificially buit ecosystem. We must recall that an ecosystem is a self sustaining unit in which materials and energy are exchanged.
If there is less carbon dioxide in the biodome then it means that there are too many plants present or too few animals in the biodome.
