Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
After a volcanic eruption, volcanic rock is present (but no soil). Which of the following states the most likely order of succession that would be seen?
A
Lichens
B
Lichens
C
Grasses
D
Lichens
Explanation: 

Detailed explanation-1: -Primary succession occurs when new land is formed or bare rock is exposed, providing a habitat that can be colonized for the first time. For example, primary succession may take place following the eruption of volcanoes, such as those on the Big Island of Hawaii. As lava flows into the ocean, new rock is formed.

Detailed explanation-2: -Primary succession occurs where no ecosystem has existed before. It is a very slow process because it begins on bare rock. A glacier that retreats leaves behind no soil. Lava from a volcanic eruption hardens into bare rock.

Detailed explanation-3: -AI Recommended Answer: The correct answer is B. C, B, A, D are the correct order of succession.

Detailed explanation-4: -The various seral stages of lithosere(succession on bare rock) are as follows: Lichens(Pioneers community)
