consumers decomposers predators producers
I gave my students this multiple choice question: Lightning from a thunderstorm strikes a 21 tree that falls to the forest floor and dies. During the next few years the dead tree undergoes many changes. What organisms are most likely responsible for the biological and chemical changes to the tree?

Only one answer is correct among these 4 choices:
- consumers
- decomposers
- predators
- producers

Could you tell me which one is correct?

decomposers
