EVERYDAY SCIENCE

Detailed explanation-1: -Scientists have estimated that there are around 8.7 million species of plants and animals in existence. However, only around 1.2 million species have been identified and described so far, most of which are insects. This means that millions of other organisms remain a complete mystery.

Detailed explanation-2: -In 2021 it listed 2.13 million species on the planet. In the chart we see the breakdown across a range of taxonomic groups – 1.05 million insects; over 11, 000 birds; over 11, 000 reptiles; and over 6, 000 mammals.

Detailed explanation-3: -Scientists estimate that there have been 1.2 million species classified and studied. However scientists estimate that they’re about 8.7 million species in existence.

Detailed explanation-4: -Over 1.5 million living animal species have been described-of which around 1 million are insects-but it has been estimated there are over 7 million animal species in total. Animals range in length from 8.5 micrometres (0.00033 in) to 33.6 metres (110 ft).

Detailed explanation-5: -Crocodiles, lizards, turtles, pythons, and other reptiles proliferated during this time, as did birds such as ducks, geese, hawks, and eagles. Larger versions of contemporary animals such as sloths, venomous lizards, marsupials, and armadillos roamed the landscape, before they were doomed by natural selection.
