Hi, This is a question on my biology test review that I don't understand. I think the answer is pine trees, but I'm not really sure. Please help!

In a barren terrestrial habitat, which of the following would be an example of a pioneer organism?

moss
pine trees
segemented worms
birds

Never mind I found out the answer is moss. Yay me. Thanks anyway!
Yay! You! Sorry I was wrong -- but I'm glad you persevered and found the right answer.
