Why does the tropical region have high biodiversity? The tropical soil...
Explanation:
The tropical region is known for its high biodiversity, and there are several factors that contribute to this phenomenon. Let's discuss each of the given options to understand why the tropical region has high biodiversity.
1. Tropical soils are high in fertility:
One of the reasons for high biodiversity in the tropical region is the high fertility of its soils. The tropical soils are rich in nutrients and organic matter, which provides an ideal environment for the growth of diverse plant species. This abundance of nutrients supports a wide range of plant life, which in turn attracts various animal species. The availability of fertile soils contributes to the overall productivity and biodiversity of the tropical region.
2. Seasonal variation in tropical climate is less:
In comparison to other regions, the tropical region experiences less seasonal variation in climate. The temperature in the tropics remains relatively stable throughout the year, with minor fluctuations. This stable climate provides a favorable environment for many species to thrive and reproduce. It reduces the risk of extreme temperature fluctuations, which can be detrimental to certain organisms. The availability of a stable climate allows for the continuous growth and development of a wide range of species, leading to higher biodiversity.
3. Solar energy is abundantly available in tropics:
The tropical region receives a high amount of solar energy due to its location near the equator. This abundant sunlight provides the necessary energy for photosynthesis, which is the primary source of food for most organisms. The availability of ample solar energy facilitates the growth of diverse plant species, which forms the foundation of the food chain. The presence of abundant solar energy supports a higher number of plant and animal species, leading to increased biodiversity in the tropical region.
4. Tropical areas had a long evolutionary time for species diversification:
The tropical region has had a long evolutionary history, which has allowed for extensive species diversification. Over millions of years, the tropical climate has provided a stable environment for the evolution and adaptation of various species. This long evolutionary time has resulted in the development of numerous unique and specialized species, contributing to the high biodiversity observed in tropical areas.
In conclusion, the tropical region has high biodiversity due to multiple factors such as the fertility of tropical soils, the absence of significant seasonal variations in climate, the abundance of solar energy, and the long evolutionary time for species diversification. These factors collectively create a conducive environment for the growth and survival of a wide range of species, resulting in the rich biodiversity of the tropics.

Why does the tropical region have high biodiversity? The tropical soil...
- Ecologists and evolutionary biologists have proposed various hypotheses about greater biological diversity in tropics; some important ones are
- Speciation is generally a function of time, 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. Hence option 4 is correct.
- Tropical environments, unlike temperate ones, are less seasonal, relatively more constant and predictable. Such constant environments promote niche specialisation and lead to a greater species diversity. Hence option 2 is correct.
- There is more solar energy available in the tropics, which contributes to higher productivity; this in turn might contribute indirectly to greater diversity. Hence option 3 is correct.
- Tropical soils are formed in areas with high annual temperature and rainfall. This climate that results in deep, highly weathered soils. The intense weathering causes these soils to be nutrient poor and low in organic matter and low in fertility. Hence option 1 is not correct.
