Final answer:
A food chain consists of producers and consumers, with organisms at different trophic levels. In this food chain, the Green Plant is a producer, the Grasshopper is a primary consumer, the Blue Bird is a secondary consumer, and the Hawk is a tertiary consumer.
Step-by-step explanation:
The food chain consists of four parts: Green Plant, Grasshopper, Blue Bird, and Hawk. The Green Plant is a producer as it is capable of making its own food through the process of photosynthesis. The Grasshopper is a primary consumer as it feeds on the Green Plant. The Blue Bird is a secondary consumer as it feeds on the Grasshopper, and the Hawk is a tertiary consumer as it feeds on the Blue Bird, occupying the highest trophic level in this food chain.
