Final answer:
Insects living in the same tree can avoid competing with each other by resource partitioning, spatial separation, and temporal separation.
Step-by-step explanation:
In order to avoid competing with each other, the three species of insects living in a certain type of tree may employ various strategies:
- **Resource partitioning**: Each species may specialize in utilizing a different type or amount of food, reducing direct competition for resources.
- **Spatial separation**: The insects may occupy different parts of the tree or utilize different microhabitats within the tree, minimizing direct interactions.
- **Temporal separation**: The insects may exhibit different activity patterns or seasonal cycles, avoiding direct competition during certain times.
