Amphibians are the most primitive group of vertebrates. Its name means “double life” (anfi – both and bios – life) and are ectothermic animals, that is, they rely on external sources of heat to control their internal balance. Besides, they’re amniotic, like fish. This means that your embryos …
Birds are hot-blooded (i.e. endothermic) terápod vertebrates that have very different characteristics and differentiate them from the rest of the animals. His ancestors were a group of theropod dinosaurs that inhabited the Earth during the Jurassic period, between 150 and 200 million years ago …

All we call flies are insects that belong to the order of diptera instead of arthropods. Despite the differences between each species, they are all identified by the average size of 0.5 cm (except for giant flies, which can reach 6 cm), a pair of membrane wings and these faceted eyes …
In any ecosystem, just as there are food chains where there are plant-producing organisms (there are no producing animals) and consuming animals, there is also a detritivorous food chain, whose purpose is to transform all organic matter from the other food chain. …
There is a branch of ecology, called synecology, that studies the relationships between ecosystems and communities of individuals. Within the synecology, there is a part in charge of the study of the relationships between living beings, including food relationships, which is summarized in the chains …
Breathing is a vital function for all living things, as even plants breathe. In the animal kingdom, the difference in breathing types lies in the anatomical adaptations of each group of animals and the type of environment in which they live. The respiratory system consists of a set of organs …
