they absorb carbon dioxide during photosynthesis and release oxygen
they store carbon in their tissues and help sequester it in the soil
they break down organic matter and release carbon dioxide into the atmosphere
they release carbon dioxide during reseparation and absorb oxygen
All of the above statements are true regarding the role of plants in the carbon cycle. Plants participate in the carbon cycle by absorbing carbon dioxide from the atmosphere during photosynthesis and releasing oxygen as a byproduct. They also store carbon in their tissues, helping to sequester it. When plant matter decomposes or is burned, they can release carbon dioxide back into the atmosphere.
