Question

Name the pioneer species that invade in primary succession on bare rock and in water.

Answer 1

Answer:

Pioneering species in case of bare rocks are lichen and small phytoplanktons.

Answer 2

The pioneer species that invade in primary succession on bare rock and in water are lichen and bacteria.

• In primary succession, newly exposed or newly formed rock is colonized by living things for the first time.
• These species helps to further break down the mineral-rich lava into soil where others, less hardy species can grow and eventually replace the pioneer species.
• Along with the wind and water, the pioneer species help weather the rock and form soil.
