Corn → Mouse → Hawk → Bacteria
Here's why:
* Corn: The corn is the producer in this food chain. It gets its energy from the sun through photosynthesis.
* Mouse: The mouse is the primary consumer. It gets its energy by eating the corn.
* Hawk: The hawk is the secondary consumer. It gets its energy by eating the mouse.
* Bacteria: Bacteria are decomposers. They break down the dead organisms (corn, mouse, hawk) and return nutrients back to the soil, continuing the cycle.
Key points:
* Energy flows through an ecosystem in one direction, from the sun to producers to consumers.
* Only about 10% of the energy from one trophic level is transferred to the next. The rest is lost as heat.
* Decomposers play a crucial role in recycling nutrients back into the ecosystem.
