It extends from the atmosphere to the bottom of the oceans. Abiotic Factors = The nonliving parts of an organism’s environment (e.g. temperature, moisture, ligh ...

The fungus provides a protective home for the algae, and gathers mineral nutrients from rainwater and from dissolving the rock underneath. ...
