What environments do fungi commonly grow in?

Fungi thrive in environments that are warm and damp because these conditions support their growth and reproduction. They require moisture and a moderate temperature to facilitate the metabolic processes that allow them to survive and proliferate. This is why you often find fungi in places like decaying organic matter, damp basements, or shower tiles, where humidity levels are higher. Additionally, the warmth helps fungi to break down substrates and access nutrients more efficiently.

In contrast, the other options suggest more restrictive environments. Fungi are not limited to laboratories, as they are present in many natural and man-made settings. They also grow on a variety of surfaces, not just human skin, which limits their habitat unnecessarily. Finally, extreme cold conditions are generally inhospitable for fungal growth, as most fungi prefer temperatures that are conducive to their active lifecycle.
