Basic Pathways Diffusion Respiration Photosynthesis the movement of atoms or molecules from an area of higher concentration to an area of lower concentration. Respiration the process in living organisms of taking in oxygen from the surroundings and giving out carbon dioxide. Photosynthesis the process by which plants use the energy from sunlight to produce sugar (C6H12O6).
Basic Pathways Eruption of Gases Burial and Sedimentation Volcanic eruptions Burial and Sedimentation Living things die, decompose and become part of the rock cycle. Weathering and Erosion Wind and water breaking down rocks.
