Definitions:

Carbon Dioxide

A colorless, odorless gas produced by burning carbon and organic compounds and by respiration. It is naturally present in air (about 0.04% by volume) and is absorbed by plants in photosynthesis.

Concentration Gradient

The gradual difference in the concentration of solutes in a solution between two regions, often resulting in diffusion.

Gas Exchange

Gas exchange is the biological process through which organisms exchange oxygen and carbon dioxide with their surroundings, critical for respiration.

Diffusion

The passive movement of molecules or particles from an area of higher concentration to an area of lower concentration, a process fundamental to many biological systems.
