### Step-by-Step Solution: 1. **Understanding Biodiversity**: Biodiversity refers to the variety of life forms within a given ecosystem, region, or on the entire planet. It encompasses species richness, genetic diversity, and ecosystem diversity. 2. **Geographical Context**: The Earth is divided into different latitudinal zones: tropical, temperate, and polar regions. Tropical regions are located near the equator, while temperate regions are situated between the tropics and the polar areas. 3. **Reason 1 - Long Evolutionary Time**: - Tropical regions have remained relatively undisturbed for a longer period compared to temperate regions. This stability allows for a longer evolutionary time frame for species to adapt, evolve, and diversify. ...
