Question

Which are the pioneer species in aquatic habitats?

• A. Fungi
• B. Algae
• C. Bryophytes
• D. Lichens

Hint:

In aquatic habitats, algae act as pioneer species, while lichens play the same role in terrestrial environments.

Answer 1

The Correct Option is B

Pioneer species initiate the colonization of unoccupied ecological niches. Within aquatic ecosystems:

• Cyanobacteria and other algae are the initial colonizers. They possess photosynthetic capabilities and exhibit resilience to adverse conditions.
• These organisms facilitate soil genesis by secreting organic matter and oxygen, thereby rendering the environment conducive for subsequent life forms.
