Question

Choose the correct sequence of transitional communities in Xerarch succession.

• A. Mosses $\to$ Lichens $\to$ Grasses
• B. Bryophytes $\to$ Forest $\to$ Shrubs
• C. Bryophytes $\to$ Herbs $\to$ Shrubs
• D. Lichens $\to$ Mosses$\to$ Herbs

Answer 1

The correct option is D Lichens $\to$ Mosses$\to$ Herbs

Xerarch Succession: Plant succession starting on bare ground or rock and culminating in a mature climax forest. The pioneer species, such as lichens and mosses, result in the gradual accumulation of soil.

Some of the important stages of succession are as follows:

1. Crustose Lichen Stage 2. Foliose Lichens Stage 3. Moss Stage 4. Herbs Stage 5. Shrub Stage 6. Xerophytic Trees Stage 7. Forest Stage

So the answer is option D 'Lichens → Mosses→ Herbs'.
