Question

Which of the following bodies have declared that the total number of plant and animal species described so far is slightly more than 1.5 million?

• A. International Union for the Conservation of Resources
• B. International Union for Conservation of Nature
• C. National Union for the Conservation of Nature
• D. Union for the Conservation of Nature and Natural Resources

Answer 1

The correct option is B International Union for Conservation of Nature

Earth is the home for a wide variety of species. The identification, classification and nomenclature of the millions of different species that have been discovered so far have been officially recorded.

This helps us maintain a count of the total number of described species belonging to different taxonomic groups and the data can be used to make a gross estimate of the total number of species that are yet to be discovered.

According to the IUCN or International Union for Conservation of Nature (2004), which is the world's oldest and largest global environmental organisation, more than 1.5 million different species of plants and animals have been described so far. This number does not reflect the total number of different species that exist on earth.

International Union for the Conservation of Resources, National Union for the Conservation of Nature and Union for the Conservation of Nature and Natural Resources do not exist.
