Question

an ecosystem has experienced a flood. which type of plants would you expect to see growing first after the flood?
○ shrubs
○ lichen
○ small annual plants
○ pine and oak trees

Explanation:

After a flood (a disturbance), ecological succession begins. Pioneer species in secondary succession (since the ecosystem still has soil) are typically small, fast - growing plants. Small annual plants have short life cycles, can germinate quickly from seeds in the soil, and are adapted to colonize disturbed areas. Shrubs and trees (like pine and oak) are later successional species. Lichen is a pioneer species in primary succession (where there is no soil, like after a volcanic eruption), not secondary succession after a flood.

Answer:

small annual plants
