Final answer:
Secondary succession typically takes over 150 years to reach a climax community.
Step-by-step explanation:
The time it takes for secondary succession to reach a climax community can vary, but on average it can take over 150 years. After a disturbance, such as a fire, the first plants to grow back are usually annual plants which are then succeeded by grasses and other pioneer species within a few years. Over time, shrubs and small trees like oak and hickory emerge as intermediate species, and it takes several decades for the ecosystem to reach a state resembling the community before the fire, known as the climax community.
