Key Idea Carbon serves as the fundamental building block of life, cycling between two main reservoirs: abiotic matter (non living CO₂ gas) and biotic matter (organic tissue).
Section 1
Moving Matter
Carbon serves as the fundamental building block of life, cycling between two main reservoirs: abiotic matter (non-living CO₂ gas) and biotic matter (organic tissue).
Photosynthesis is the specific mechanism that transfers carbon from the abiotic reservoir to the biotic reservoir. It extracts carbon atoms from the atmosphere and integrates them into the organic structures of living things.
Section 2
Carbon Fixation
The transformation of inorganic gas into organic solid is known as carbon fixation. During photosynthesis, producers bond loose carbon atoms from CO₂ gas to form solid carbohydrate molecules.
This process represents a change in the state of matter from gas to solid. It is the primary pathway for carbon entry into the food web, allowing organisms to build physical mass from atmospheric gases.
