• Erosion breaks rocks apart into smaller pieces and decomposition of pioneer species adds nutrients to the ground (soil formation)

• Small annuals (plants) start to appear

• Grasses and ferns (perennials) appear

• Shrubs and bushes appear

• Softwoods such as conifers (trees with cones) appear

• Hardwoods such as oak, maple, hickory, walnut, and cherry trees

Quicker than primary succession since the soil still remains.

Multiple Choice
