Question

1. what is the relationship between increased carbon in the ocean and increased carbon in the soil? how else might carbon be transferred to soil?

Explanation:

When carbon in the ocean increases, some marine organisms (like plankton) take up carbon. When these organisms die, they can sink to the ocean floor and over time, through geological processes, contribute to carbon in sediments. These sediments can eventually be uplifted (e.g., through tectonic activity) and become part of land - based soil.
Other ways carbon can be transferred to soil include:

• Plant photosynthesis: Plants take in carbon dioxide ($CO_2$) from the atmosphere. When plants die and decompose, the carbon they have fixed is transferred to the soil.
• Decomposition of organic matter: Dead animals, fungi, and other organic materials decompose. During decomposition, carbon - containing compounds are broken down and carbon is released into the soil.
• Root exudation: Plant roots release organic compounds (which contain carbon) into the soil.

Answer:

The relationship is that carbon from the ocean can eventually reach soil through processes like sedimentation and geological uplift. Other ways carbon is transferred to soil are through plant photosynthesis and decomposition, and root exudation.
