Which of the following organisms can initiate ecological succession even in bare rocks?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Lichens.
Lichens are organisms that can initiate ecological succession even on bare rocks. They are capable of surviving in harsh, nutrient-poor environments by breaking down rock surfaces and gradually creating a thin layer of soil. This process allows other plants to take root and gradually leads to the development of a more complex ecosystem. Lichens are often the first organisms in primary succession, paving the way for mosses, grasses, and eventually larger plants like trees to establish themselves.
