Most living organisms cannot survive at temperatures above `45^@` How are some microbes able to live in habitats with temperatures exceeding `100^@`

Explanation

**Step-by-Step Solution:**

1. **Understanding the Temperature Limitations of Most Organisms:**
- Most living organisms have a maximum survival temperature of around 45°C. Beyond this temperature, their biological processes begin to fail.

2. **Denaturation of Enzymes:**
- At temperatures above 45°C, the proteins, especially enzymes, in these organisms begin to denature. Denaturation is a process where the structure of proteins is altered, leading to a loss of function. This disruption in enzyme activity is often fatal for the organism.
