How Many Biodiversity Hotspots Are There in India? India has four global biodiversity hotspots: the Himalaya, Indo-Burma, Western Ghats–Sri Lanka, and Sundaland . These regions are recognized for their exceptional biodiversity, endemic species, and conservation importance. Quick Answer: India is associated with 4 biodiversity hotspots . 1. Himalaya 2. Indo-Burma 3. Western Ghats–Sri Lanka 4. Sundaland What Is a Biodiversity Hotspot? A biodiversity hotspot is a region that contains a high concentration of unique biological diversity and is under significant threat from habitat loss and other pressures. The hotspot concept is particularly useful for conservation because protecting these areas can help conserve many species that are found nowhere else. Therefore, a biodiversity hotspot is not simply a place with many species. Species richness, endemism and conservation threat are important aspects of the concept. 📚 NEET Biology Study Hub Looking for more NCERT-foc...

AP Bio Unit 8.6 Review: What is Biodiversity? (The 3 Levels) Biodiversity  Biodiversity is the variability of life on Earth . It can be measured on various levels, for example, genetic variability , species diversity , ecosystem diversity , and phylogenetic diversity. [ 1 ] Diversity is not distributed evenly on Earth — it is greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator . Tropical forest ecosystem s cover less than one-fifth of Earth's terrestrial area and contain about 50% of the world's species. [ 2 ] There are latitudinal gradients in species diversity for both marine and terrestrial taxa .

Which Ecological Pyramid is Always Upright? Explanation with Examples Which Ecological Pyramid is Always Upright? Explanation with Examples Ecological pyramids are graphical representations of the relationship between different trophic levels in an ecosystem. One of the most commonly asked questions is: Which ecological pyramid is always upright? Answer: Pyramid of Energy is Always Upright The Pyramid of Energy is always upright in any ecosystem. This is because energy decreases as we move from lower to higher trophic levels due to the 10% law of energy transfer. Why is Pyramid of Energy Always Upright? Only about 10% of energy is transferred from one trophic level to the next. Remaining 90% energy is lost as heat during metabolic processes. Therefore, energy content is always highest at the producer level and lowest at the top carnivore level. Comparison of Ecological Pyr...
