Final answer:
Insects make up more than 50% of all known organisms, displaying incredible species diversity with estimates of up to 10 million species worldwide. They are found in nearly every habitat, making them a predominant form of life on Earth.
Step-by-step explanation:
Insects are the most diverse group of animals on Earth, encompassing a massive proportion of all named species. With estimates ranging up to more than 10 million insect species worldwide, they are a dominant form of life, especially in terrestrial habitats. In terms of species diversity, insects are unparalleled, and they can be found in almost every environment across the globe.
Examples of insects' diversity include the vast number of beetle species, which is about 350,000 known types. However, due to the sheer number of insect species, it is generally accepted that insects comprise more than 50% of all known organisms, providing a testament to their vast species diversity and ecological importance.
The exact percentage of all named species comprised by insects can vary based on current scientific discoveries, but generally, it is documented that insects make up an overwhelming majority of biodiverse life forms on our planet.
