Answer 1

B. A newly formed volcanic island.

Primary succession is the first stage of the ecological succession of plant life from abiotic land with no soil to fully support plant ecosystems. In primary succession, pioneer plants like mosses and lichen, start to "normalize" the habitat, creating conditions nearer the optimum for plant growth. These pioneer plants are then dominated by more complex plants like grasses and shrubs. A good example of primary succession takes place after a volcano has erupted, since the volcano has no soil. The soil must be created by the mosses and lichens, which will break down the rock into soil for other plants to grow.
