Final answer:
Mesquite is a decomposer, grasshopper is a producer, elf owl is a predator, and vulture is a consumer.
Step-by-step explanation:
In this question, the terms mesquite, grasshopper, elf owl, and vulture are given in relation to their roles in an ecosystem. The correct match between these organisms and their roles are:
- Mesquite - Decomposer
- Grasshopper - Producer
- Elf owl - Predator
- Vulture - Consumer
Decomposers like mesquite break down dead organic matter and recycle nutrients back into the ecosystem. Producers like grasshoppers undergo photosynthesis to produce food. Predators like elf owls feed on other organisms, while vultures are consumers that obtain their energy by scavenging on dead animals.
