Solution
- Pioneer Community:
- The species that invade a bare area, are called pioneer species.
- In primary succession on rocks these are usually crustose lichens which are able to secrete acids to dissolve rock, helping in weathering of rocks and soil formation.
- These pave the way for bryophytes, mosses that are able to take hold in the small amount of soil.
- Climax Community:
- They are, with time, succeeded by herbaceous plants, and after several more stages, ultimately a stable climax forest community is formed.
- The climax community remains stable as long as the environment remains unchanged.
