Vedclass · Answer

(B) In ecological succession,the pioneer species are the first organisms to colonize a previously barren area. Lichens are known as pioneer species in $Lithosere$ (succession on bare rocks). They secrete acids to dissolve rock,helping in the process of weathering and soil formation,which eventually allows other plants to grow. Since $Lithosere$ is a type of $Xerosere$ (succession in dry areas),both are technically correct,but $Lithosere$ is the most specific and accurate term for succession starting on bare rocks.

The presence of lichens as pioneer species can be observed in which of the following successions?
