These easily tailored papers can be printed and used in the classroom, as homework or for revision purposes. How is biodiversity important for ecosystem functioning? Microscopic examination of the cells reveals no evidence of membrane-enclosed organelles. This provides rich specialization and leads to greater species diversity. What is the result of loss of biodiversity in a region? The current rates of extinction is estimated to be faster than the pre-human times because of our activities. For the welfare of human, we want to deliberately make such pathogenic species extinct.
