Q.8	Biodiversity is all the different kinds of life you'll find in one area—the variety of animals, plants, fungi, and even microorganisms like bacteria that make up our natural world. Each of these species and organisms work together in ecosystems, like an intricate web, to maintain balance and support life. Usually, three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Biodiversity supports human and societal needs, including food and nutrition security, energy, the development of medicines and pharmaceuticals, and freshwater, which together underpin good health. It also supports economic opportunities and leisure activities that contribute to overall well-being. Which one is present in the most number among the following a- Angiosperm b- Mosses c- Algae d- Lichen The greatest biodiversity on earth is probably on a- Indo- Burma b- Himalayan range c- Sundarban d- Amazon rainforest Alexander Von Humboldt worked on a- Latitudinal gradient b- Causes of loss of biodiversity c- Species area relationship d- Rivet popper hypothesis Assertion: IUCN prepares red list. Reason: red list contains information of extinct species. Both assertion and reason are correct and the reason is the correct explanation of assertion. Both assertion and reason are correct and the reason is not a correct explanation of assertion. Assertion is true but the reason is false Assertion is false but the reason is true.	4M
Q.9	(a) Mention two examples of animals that have become extinct in the recent past. (b) Write down the four major causes of loss of diversity in detail.	5M
