Concept in Definition ABC

Being perhaps the most abundant living beings on planet Earth, insects are a type of animal invertebrate (which means it has no bones) that can vary greatly in terms of shape and size although normally they are not usually too large and may even some to be really microscopic. Insects are undoubtedly the owners of planet Earth and this does not have to do only with the fact that they are the most numerous (it is esteem that there may be more than 200 million of them for each human being), but also because deep down they are responsible for carrying out very important tasks such as decomposition to assimilate the organisms that no longer have life, among other things.

Insects belong to the phylum Arthropoda and to the class Insecta. Etymologically, the word insect comes from Latin, a language in which insectus means "party in the middle" and this applies in the case of these animals to the shape of their organism, divided into two central parts: a rear and a front. Other

features of insects is that they all have antennae, numerous legs (which can be more or less depending on the type of insect or even the species) and wings that can sometimes be very tiny. In this sense, it is very important clarify that some living beings such as spiders and other arthropods do not fall within the definition of insects and in fact do not share the class with them. They differ mainly in the shape of the body, as well as the absence of wings and the number of legs that they can have, in some cases like centipedes, very many.

Unlike the rest of the living beings, insects are the only ones that have known how to adapt to all climates, biomes, environments and geographies, so even in a frozen state we can find microscopic forms of insects that survive very low temperatures. This makes them very resistant to all types of external shock and that is why it is not so wrong either. think that eventually insects will outlive man due to their high endurance.
