small trees and wildflowers
grasses and shrubs
lichens and mosses
tall trees with thick brush
previous

Explanation:

Primary succession begins in an area with no soil. Lichens and mosses are pioneer species that can grow on bare rock. They break down the rock to form soil, which allows other plants to grow later. Tall trees with thick brush come in later stages. Grasses and shrubs come after the pioneer species but before the tall trees. Small trees and wildflowers also come after the pioneer species. Lichens and mosses are the first to appear in primary succession.

Answer:

lichens and mosses
