Final answer:
The USDA is responsible for overseeing conservation and environmental activities in agriculture and food production, while the EPA monitors water quality standards and pollution prevention.
Step-by-step explanation:
The governmental organization that monitors conservation and environmental activities related to agriculture and food production is the United States Department of Agriculture (USDA). The USDA oversees numerous programs that promote ecological balance and conserve biodiversity with various initiatives such as the National Organic Program, which is evident by the use of the USDA organic logo on products that meet their standards. The agency ensures that organic agricultural practices follow regulations intended to benefit the environment. Furthermore, the Environmental Protection Agency (EPA) is another agency that plays a significant role in monitoring and establishing water quality standards, regulation of pesticides, and preventing pollution with a focus on protecting the environment and human health.
