Question

An undersea volcano erupts, forming a new island made of lava and ash. Several years later, plants begin to grow from seeds found in bird droppings. What kind of succession has occurred?

a) Primary succession
b) Secondary succession
c) Tertiary succession
d) Regressive succession

Answer 1

Primary succession has occurred in this scenario, as new land is formed from the eruption of an undersea volcano and pioneer species gradually colonize the area, leading to the development of a stable ecosystem over time.

Step-by-step explanation:

The kind of succession that has occurred in this scenario is Primary succession.

Primary succession occurs when new land is formed or rock is exposed, such as in the case of an undersea volcano eruption forming a new island.

The process starts with the colonization of pioneer species like lichens and certain plants that can grow in the harsh conditions.

Over time, these pioneer species help break down the lava into soil, allowing for the growth of more complex and competitive species, eventually leading to a stable and diverse ecosystem.
