Greenhouse Gas: These are gases in Earth's atmosphere that trap heat. They let sunlight pass through the atmosphere but prevent Earth's heat from escaping into space - like how glass windows keep your house warm during winter.
This is the process where organisms convert glucose back into energy for use in their cells, producing CO2 as a waste product - this would be like eating and digesting our baked bread from earlier!
Carbon Cycle: The series of processes by which carbon compounds are interconverted in the environment, chiefly involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration - imagine this as nature’s way of recycling ingredients for baking!
