And when the end of the growing season comes, the plant dies and decomposes, and then all that work they did to suck out the CO2 from the atmosphere and make carbon-based biomass is now basically going right back up in the atmosphere as CO2.
E quando o período vegetativo chega ao fim, a planta morre e decompõe-se, e todo o seu trabalho árduo, a absorver CO2 da atmosfera e a usá-lo para criar biomassa perde-se, regressando à atmosfera, sob a forma de CO2.
