To complete the food chain with the correct terms, the sequence would typically go as follows:
- Oak Tree (Producers) → provides energy through photosynthesis.
- Leaves (Part of the Oak Tree - Producers) → the specific part of the plant consumed by herbivores.
- Caterpillar (Primary Consumer) → eats the leaves.
- Treecreeper (Secondary Consumer) → eats the caterpillar.
- Hawk (Tertiary Consumer) → eats the Treecreeper.
So you would match them like this:
- Oak Tree → Producers
- Leaves → Part of Oak Tree (Producers)
- Caterpillar → Primary Consumer
- Treecreeper → Secondary Consumer
- Hawk → Tertiary Consumer
Arrange them according to the food chain structure you've provided.
