### Step-by-Step Solution: 1. **Understanding Biodiversity**: Begin by defining biodiversity, which refers to the variety of life forms in a particular habitat or ecosystem. It includes the number of different species, genetic diversity, and ecosystem diversity. 2. **Geographical Context**: Recognize the geographical locations being discussed: the equator and the poles. The equator is located at 0 degrees latitude and is characterized by a warm climate, while the poles (North and South) are located at 90 degrees latitude and have extremely cold climates. 3. **Species Diversity at the Equator**: Acknowledge that the equatorial regions are known for their high species diversity. This is due to the warm climate, abundant sunlight, and consistent rainfall, which create ideal conditions for a wide variety of species to thrive. ...
