But too much water can cause the material to swell and can promote the growth of organisms if they are present.

Several explanations have been put forward, some of which involve water or even the growth of organisms.

Phototropism is the growth of organisms in response to light.

If the acidity were far off normal, conditions might favor unusual growth of organisms.

Local conditions within the colony change, and check the growth of organisms.

The fluid is placed in culture media in the laboratory and observed for growth of organisms.

Now those who understand the growth of organisms are aware that evolution depends on adaptation to environment.

Some involve water or even the growth of organisms.

A normal result is no growth of organisms.

Keep humidity levels low and fix leaks to reduce the growth of organisms such as mold.
