What does a plant need to take in from the environment to live? a. oxygen b. carbon dioxide c. argon d. nitrogen gas

"B" Carbon Dioxide. Plants take in carbon dioxide from the atmosphere and then release oxygen. That is why it is so important that we have plants and trees. We support each other in a cycle. We take in oxygen and release carbon dioxide, and they take in carbon dioxide and release oxygen.

I hope this helps!
