How does biodiversity vary with respect to latitude, from the equator towards the poles? |
decreases increases remains the same first decreases, then increases |
decreases |
The correct answer is Option (1) - decreases The diversity of plants and animals is not uniform throughout the world but shows a rather uneven distribution. For many group of animals or plants, there are interesting patterns in diversity, the most well- known being the latitudinal gradient in diversity. In general, species diversity decreases as we move away from the equator towards the poles. With very few exceptions, tropics (latitudinal range of 23.5° N to 23.5° S) harbour more species than temperate or polar areas |
