A species-area curve is drawn by plotting the number of species against the area. How is it that when a very large area is considered the slope is steeper than that of smaller areas?

Explanation

To understand why the slope of the species-area curve is steeper for larger areas compared to smaller areas, we can break down the explanation into several steps:

### Step-by-Step Solution:

1. **Understanding the Species-Area Relationship**:
- The species-area curve illustrates the relationship between the size of a habitat (area) and the number of species it can support. Generally, as the area increases, the number of species also increases.

2. **Graph Representation**:
...
