Question

Green plant to grasshopper to blue bird to hawk
Producer
Primary consumer
Secondary consumer
Tertiary consumer

Answer 1

In the food chain you provided, the roles of the organisms in terms of trophic levels are as follows:

1. **Producer**: Green plant (This is the primary source of energy in the ecosystem through photosynthesis).

2. **Primary Consumer**: Grasshopper (This organism feeds on the green plants and thus derives energy directly from the producers).

3. **Secondary Consumer**: Blue bird (This bird feeds on grasshoppers, thus getting its energy from the primary consumers).

4. **Tertiary Consumer**: Hawk (This predator feeds on blue birds, placing it at the top of the food chain in this scenario).

So the order is:
- Green plant: Producer
- Grasshopper: Primary consumer
- Blue bird: Secondary consumer
- Hawk: Tertiary consumer
