Solution
The correct option is D both a and b
More than 1.5 million species of plants and animals have been identified and described by biologists so far, as stated by the IUCN (2004).
The currently available records on the identified species tell us that more than 70% of all the recorded species are animals and about 22% of the recorded species belong to plants and fungi.
Amongst plants, the highest species diversity is shown by angiosperms (flowering plants), followed by algae, mosses (bryophytes) and ferns (pteridophytes).
Fungi are approximately as diverse as the angiosperms. In fact, the total number of fungi species in the world is more than the sum total of the number of species belonging to fishes, reptiles, amphibians and mammals.
