Which one of the following has the highest number of species in nature?More than 70 per cent of all the species recorded are animals, while plants (including algae, fungi, bryophytes, gymnosperms and angiosperms) make up no more than about 22 per cent.
Among animals, insects are the most species-rich taxonomic group, forming more than 70 per cent of the total.
That means out of every 10 animals on this planet, 7 are insects.
The number of fungal species is larger than the combined total of fishes, amphibians, reptiles and mammals, but is still much smaller than that of insects.
Angiosperms and birds have far fewer species than insects.
Hence insects have the highest number of species.
