Among the animal on the planet, the species rich group making more than 70% is
Fishes
Mammals
Insects
Reptiles
The Correct Option is C
Solution and Explanation
Among the animal groups on the planet, the species-rich group making more than 70% is "Insects." Insects are the most diverse group of animals, comprising approximately 70% of all known animal species. This tremendous diversity is due to their adaptability to various habitats and their ability to fill a wide range of ecological niches. Fishes, mammals, and reptiles have lower species richness compared to insects.
Top Questions on Biodiversity and Conservation
- In nature, populations of different species in a habitat do not live in isolation but interact in many ways. Depending on the outcome, these interactions between two species are classified as competition, predation, parasitism, commensalism, amensalism, and mutualism. Through these interactions, trophic energy transfer is facil itated. Some predators help in controlling their prey populations, whereas plants have evolved diverse morphological and chemical defenses against herbivores.

Biodiversity and Conservation
The term ‘biodiversity’ is derived from the two words- ‘bios' which means life and ‘diversity’ i.e, differentiation or variation. Edward Wilson, the sociobiologist was the first to popularise the term ‘biodiversity’ in the year 1992. The term implies the occurrence of various plants and animals along with their variants such as biotypes, ecotypes and genes on earth. In our biosphere, the immense diversity or heterogeneity remains not only at the species level but also, at every level of biological organization that ranges from macromolecules in the cells to biomes.
Biodiversity and Conservation is a topic covered under the fifteenth chapter and Unit 5 of NCERT class 12 biology.
