Final answer:
In an ecological context, marine biologists, ecologists, and environmental scientists are the target group used to evaluate dead zones, which are areas of low oxygen in water bodies where marine life cannot thrive.
Step-by-step explanation:
The inquiry about which target group is used to evaluate the dead zone seems to pertain to an ecological or environmental science context rather than archery. In ecology, a dead zone refers to an area within a body of water with low oxygen concentrations where most marine life cannot survive. To assess the extent or impact of a dead zone, scientists typically measure factors such as dissolved oxygen levels, aquatic life diversity, and the presence of specific biological indicators like tolerant or sensitive species. These biotic and abiotic measurements help determine the health and quality of the aquatic ecosystem. Therefore, the target group used to evaluate a dead zone would include marine biologists, ecologists, and environmental scientists who specialize in aquatic habitats.
