Metazoans
Multicellular, heterotrophic organisms belonging to the animal kingdom. Unlike single-celled organisms like protozoans, metazoans are composed of multiple cells, which are subdivided into specialised tissues and organs capable of performing a range of functions.
Metazoans have complex anatomies and, as a rule, are capable of active motion, allowing them to explore their surroundings. They feed on other organisms or organic substances and can reproduce sexually or asexually. The metazoans encompass a broad range of animals, insects and fishes, including mammals and birds. They play an important part in the ecosystems where they are found – as predators, prey, pollinators, and as part of the food web.
