Answer: Succession
Succession on bare, previously uncolonized substrate (e.g. new lava flows)?
Answer: Primary succession
Succession on bare soil where a community previously existed (e.g. after fire)?
Answer: Secondary succession

Play it as a class game
Play this set opens it in splycr, where you can host it for your class straight away. Hosting needs no account: put the room code on the projector, and students join from a phone with the code and their first name. Each question plays as multiple choice, and the three wrong options are other answers from the same set.
