### Step-by-Step Solution: 1. **Understanding the Concept of Biodiversity and Productivity**: - Biodiversity refers to the variety of life in a particular ecosystem, including the different species of plants, animals, and microorganisms. - Primary productivity is the rate at which biomass is produced by primary producers (usually plants) in an ecosystem. 2. **David Tilman's Research**: - David Tilman conducted experiments that showed a positive correlation between biodiversity and primary productivity. His findings indicated that ecosystems with higher biodiversity tend to have higher productivity due to increased stability and resilience. ...

What is so special about tropics that might account for their greater biological diversity? a. Unlike temperate regions subjected to frequent glaciations in the past, tropical latitudes have remained relatively undisturbed for millions of years and thus, had a long evolutionary time for species diversification. b. Temperate environments, unlike tropical ones, are less seasonal, relatively more constant and predictable. Such constant environments promote niche specialization and lead to a greater species diversity. c. There is more solar energy available in the tropics, which contributes to higher productivity, this in turn might contribute indirectly to greater diversity.
