From which source can specific information on endangered species be obtained?

The most comprehensive and reliable source for specific information on endangered species is the U.S. Fish and Wildlife Service. This agency is dedicated to the conservation of endangered and threatened species and their habitats and provides extensive resources, guidelines, and data regarding the status and protection of these species.

Pesticide labels may contain cautionary information regarding the potential effects of pesticides on non-target organisms, which could include endangered species, but they may not provide in-depth or specific data on conservation status or federal protections. Similarly, bulletins produced by the U.S. EPA can offer insights into regulations and environmental impacts related to pesticides but are generally broader in scope and less focused on individual species.

Choosing all sources as correct emphasizes the importance of utilizing multiple avenues of information for comprehensive understanding, but for authoritative guidance specifically on endangered species, the U.S. Fish and Wildlife Service stands out as the primary source.
