circulation digestion reproduction respiration
I gave my students this multiple choice question: Fungi recycle leaves in forests. Fungi release chemicals onto the leaves to break them down into smaller particles. The fungi use the small particles for growth. Which process allows fungi to obtain the nutrients they need from dead leaves?

Only one answer is correct among these 4 choices:
- circulation
- digestion
- reproduction
- respiration

Could you tell me which one is correct?

digestion
