CO2 levels fluctuate seasonally and throughout the day due to photosynthesis (daytime only) and respiration (continuous), resulting in higher levels at night and in winter, and lower levels during the day and in summer.
Los niveles de CO2 fluctúan estacionalmente y a lo largo del día debido a la fotosíntesis (solo durante el día) y la respiración (continua), lo que resulta en niveles más altos por la noche y en invierno, y más bajos durante el día y en verano.
| Front | CO2 levels fluctuate |
|---|---|
| Back | CO2 levels fluctuate as photo only occurs in presence of light (daytime) so CO2 removed from atm only during day, respiro occurs throughout day/night, so CO2 released at relatively constant rate into atm, so CO2 levels higher at night than during day, CO2 levels in atm lower in summer than winter as photo rates faster |
