Okie, dokie. There are 9 official land biomes (that I know of): Tundra, boreal forest, temperate forest, woodlands, grasslands, deserts, tropical savannas, tropical seasonal forests, and tropical rain forests.
Judy Hopps is a bunny so she could live either in the Temperate grassland or in the tropical seasonal forest. Grassland: the soil is fertile enough to support a thick cover of grass, providing enough food for the bunnies to eat and survive within. Forest: enough food as well because enough rain falls to sustain plants that the bunny can feed off of.
