The Fairfax County Public Schools website has a page called “Study of Northern Virginia Ecology”, which has fact sheets for various plants and animals in Virginia.

All of the fact sheets have a section at the bottom called “Relationships with Nature”. Each animal’s page lists examples its prey/food, predators, shelter, and any other relationships. Each plant’s page lists examples of animals that use it as a food source, animals that use it as a shelter, associations with other plants, and any other relationships.
