Heat loss or heat gain depends upon the surface area of the organism's body. Explain with the help of a suitable example.

Explanation

To explain how heat loss or heat gain depends upon the surface area of an organism's body, we can break down the concept step by step:

### Step-by-Step Solution:

1. **Understanding Heat Exchange**:
- Heat exchange in organisms occurs through their surface area. The larger the surface area relative to volume, the more heat an organism can lose or gain from the environment.

2. **Surface Area to Volume Ratio**:
