Carbon is the fundamental building block for all known life on Earth, as evidenced by its role in organic chemistry and biochemistry [1], [2], [3]. Furthermore, the cycling of carbon is a critical ecological process occurring across the biosphere of Earth [4], and its chemical properties are compared to other elements within the context of Earth's crustal abundance [5], [6].
