What layer does a hyena live on?

Hyenas primarily inhabit the savanna and grassland ecosystems, where they often live at ground level. They are known to den in burrows or caves, which can be found in various terrains, including rocky areas and open plains. Additionally, they may also be seen near forest edges or in semi-arid regions, depending on their prey availability. Overall, hyenas are versatile in their choice of habitat but predominantly thrive on the ground level of their environments.
