Which of the following are pioneer species on recently glaciated rock?
Spruce and fir trees Lichens and mosses Herbs and shrubs Evergreens and fir trees Maples and redwoods
Pioneer species on recently glaciated rock are typically organisms that can colonize bare substrates and initiate the process of ecological succession. In this context, the correct answer would be lichens and mosses. These organisms are well-known for their ability to survive in harsh conditions and help in soil formation by breaking down the rock and contributing organic material as they die and decompose.
