Question

Mention the role of pioneer species in primary succession on rocks.

Answer 1

In primary succession pioneer species like lichen, algae and fungi as well as other abiotic factors like wind and water start to "normalize" the habitat. Primary succession begins on rock formations, such as volcanoes or mountains, or in a place with no organisms or soil.

Answer 2

Answer:

Pioneer succession is an ecological succession that begins in the area which is not previously occupied by any living species. It typically initiate in the barren land.

Explanation:

• An ecological succession is a change or group of changes that occurs in the living species of the area with respect to the changes occurring in the non-living environment with respect to time until the ecosystem attains stability.
• A pioneer species like lichen and mosses grows on the rocks and initiate the primary succession in the area.
• The lichen secrete acid which helps in withering of the rocks and results in production of soil which can be used by the plant species to colonize over the barren land.
