small annual plants

The correct answer will be annual plants.

Explanation:

When an ecosystem experiences a natural catastrophic event such as flood, fire it causes the disturbance and damage of the existing community. The disturbed area does not remain devoid for long time but undergoes series of community changes, which create mix of species through a process called secondary succession.

The first colonizers will be small annual plants, which will be succeeded by grasses, perennials, shrubs and then large trees which will form a stable community on damaged land.

Thus, small annual plants is the correct answer.
