Pioneer species thrive during the early stages of ecological succession.

Pioneer species, such as hardwood trees, thrive during the final stages of ecological succession.

Detailed explanation-1: -Pioneer species are hardy species which are the first to colonize previously disrupted or damaged ecosystems. For example, After the lava cooled and hardened, it would be very difficult for plants to survive, because of the lack of soil.
Detailed explanation-2: -Pioneer species are organisms that are made up of only one cell. Pioneer species thrive during the early stages of ecological succession.
Detailed explanation-3: -The first stage of succession involves pioneer species. In primary succession, pioneer plants are those that can grow without soil, such as lichens. Lichens begin breaking down a rock. Seasonal cycles of freezing and thawing form cracks in the rock.
Detailed explanation-4: -Pioneer communities help enrich the soil. As generations of the mosses or lichens die, their remains decompose and are added to the soil. The soil is then able to support a greater variety of plant life.
