Three reasons why tropics show greatest levels of species diversity:
1. Stable climate: The tropics have a warm, stable climate with little seasonal variation. This consistency allows for the evolution and survival of a wide range of species.
2. High primary productivity: The tropical regions, especially rainforests, have high primary productivity due to abundant sunlight, rainfall, and warm temperatures, supporting a wide range of organisms.
3. Ecological niches: The tropics have a diverse range of habitats, creating multiple ecological niches where different species can evolve and coexist.
Study the pie chart given below, representing the global biodiversity and proportionate number of species of major taxa.
Answer the following questions:
[a] Identify 'X' and 'Y' in the given pie chart.
[b] Which one of the two 'X' or 'Y' is the most species-rich taxonomic group and by what percentage?
[c] Name the level of Biodiversity represented by the following:
