• It begins on a bare rock

Answer 1

It occurs on a deforested site

Explanation:

The growth of different biotic communities at the same location until a peak community emerges is referred to as biotic or ecological succession. The ecological succession on a primary base region like as a rock, outcrop, or glacial moraline is known as primary succession. It takes a long time, perhaps a thousand years or more. Secondary succession is biotic succession on a secondarily barren area, such as a forest fire or deforestation-devastated area. For grassland, it takes 50 to 100 years, and for forest, it takes 100 to 200 years. Because of their underground rhizomes, ferns are usually the first plants to emerge following a forest fire. Weeds like Sphagnum, Lantana, Eichhornia, and Eupatorium prevent secondary succession from taking place.
