How does a koala depend on nonliving things in the ecosystem?

Koalas depend on nonliving things in their ecosystem primarily through their habitat, which includes elements like soil, water, and air. The soil supports eucalyptus trees, their main food source, while water is vital for hydration. Additionally, clean air is essential for their overall health and well-being. Together, these nonliving components create a suitable environment for koalas to thrive.
