The living thing in the given environment is fungus (mushroom).

The living thing in this list is the fungus (mushroom). To determine this, we need to look at the characteristics of living things. Living things are organisms that possess certain properties such as growth, reproduction, ability to respond to stimuli, need for energy, and adaptation.

In the case of the options you provided:

1. Soil (clay): Soil is non-living. It is made up of minerals, organic matter, water, and air but does not possess any of the characteristics of living things.

2. Air (wind): Air is also non-living. It consists of a mixture of gases, primarily nitrogen, oxygen, carbon dioxide, and traces of other gases. While it is essential for supporting life, air itself is not a living thing.

3. Water (river): Water is non-living. It is a compound composed of hydrogen and oxygen atoms, necessary for life, but it does not have the properties of a living organism.

4. Fungus (mushroom): Fungus, including mushrooms, is a living thing. Fungi are eukaryotic organisms that obtain nutrients by decomposing organic matter. They possess cellular structures, reproduce, and respond to their environment.

Therefore, among the options provided, only fungus (mushroom) meets the criteria of a living organism.
