Matter and Energy in Organisms and Ecosystems 1 Bellwork 21Claim: Plants need carbon dioxide to survive.

Evidence: Based on my observations in the lab, I know plants need carbon dioxide because the discs in the carbon dioxide water float and the discs in the regular water sink.

What needs to be added to this evidence to help support the claim?
