Which process involves carbon moving directly from the biosphere into the geosphere? (1 point) the photosynthesis of a plant the weathering of rocks by a river the decomposition of plants on the forest floor the eruption of a volcano

When plants die and decompose on the forest floor, their carbon compounds break down and can seep into the soil, enriching it with carbon. Over time, this can lead to the formation of fossil fuels, effectively transferring carbon from the biosphere into the geosphere. This process isn't just an isolated affair; it’s part of the larger carbon cycle that constantly reshapes our environment. Decomposed organic matter contributes to soil health and fertility, playing a crucial role in sustaining new plant life and maintaining ecosystem balance. It's nature's way of recycling!
