What organisms are responsible for absorbing carbon from the atmosphere?

Plants, particularly through the process of photosynthesis, are the primary organisms responsible for absorbing carbon dioxide from the atmosphere. Trees, shrubs, and grasses take in CO2 and convert it into organic matter while releasing oxygen. Additionally, phytoplankton in oceans play a crucial role in carbon absorption, as they account for a significant portion of global photosynthesis. Some microorganisms in soil and oceans also contribute to carbon cycling and storage.
