Among the animal on the planet, the species rich group making more than 70% is __________.

Insects

The correct answer is Option (3)-Insects

More than 70 percent of all the species recorded are animals, while plants (including algae, fungi, bryophytes, gymnosperms and angiosperms) comprise no more than 22 percent of the total. Among animals, insects are the most species-rich taxonomic group, making up more than 70 per cent of the total. That means, out of every 10 animals on this planet, 7 are insects.
