Why is the maximum diversity of life form in between the tropic of cancer and tropic of Capricorn?

The maximum diversity of life forms between the Tropic of Cancer and the Tropic of Capricorn is primarily due to the region's warm climate, consistent sunlight, and abundant rainfall, which create ideal conditions for a wide variety of ecosystems, such as rainforests and coral reefs. This area, often referred to as the tropics, supports complex food webs and high species richness, as organisms have evolved to exploit the diverse habitats and resources available. Additionally, the relatively stable environmental conditions promote year-round growth and reproduction, further contributing to biodiversity.
