A Growth trajectory across four developmental stages (Pioneer, Young, Maturing, and Steady State), with the dashed red line indicating a sigmoidal growth curve. B Carbon sequestration rate over the complete life cycle (Seeds, Pioneer, Young, Maturing, Steady State, Aging, and Dead). The pink curve traces the sequestration rate, which peaks at the Maturing stage and drops below zero (horizontal black line) during Aging and Death.
