The process that involves carbon moving directly from the biosphere into the geosphere is **the decomposition of plants on the forest floor**. During decomposition, organic matter is broken down, and carbon is released into the soil, which is part of the geosphere.
The other options involve different interactions:
- The eruption of a volcano primarily releases carbon dioxide and other gases from the geosphere to the atmosphere.
- The weathering of rock by a river does not involve a direct transfer of carbon but rather the physical or chemical breakdown of rocks.
- Photosynthesis is the process where plants absorb carbon dioxide from the atmosphere, thus moving carbon from the atmosphere into the biosphere, not the geosphere.
