Here's why:
* Water is essential for their life cycle: Mosses need water for reproduction (releasing spores) and for absorbing nutrients.
* They lack vascular tissue: Unlike plants with roots and stems, mosses don't have a system to transport water efficiently. They rely on direct absorption through their leaves.
* Their small size and thin leaves: These features make them prone to desiccation (drying out) in dry environments.
Therefore, you'll find mosses in moist habitats like:
* Forests: Shaded and humid areas provide ideal conditions.
* Bogs and swamps: These wetlands offer ample water and nutrients.
* Moist rocks and walls: They can cling to surfaces with enough moisture.
While mosses can survive brief periods of dryness, they won't flourish in truly arid climates. If you water the soil in a dry environment, it might help mosses survive for a short while, but they won't thrive long-term.
