thomaster · Answer

Do you know what a pioneer species is?

anonymous · Answer

yep like lichens, moss, and grasss, etc

anonymous · Answer

pioneer species is like bacteria

thomaster · Answer

Well the actual explanation would be organisms who colonize on previously disrupted ecosystems, like rocks or lava during primary succession. And an oak tree is not one of those species, so you're right :)

Never just just give an answer, always provide an explanation. We discourage giving out answers without letting the asker at least take some part in the analysis. The aim of this site is to teach, not to provide free answers.
