eläinorganismeihin

Eläinorganismeihin refers to animal organisms in Finnish. This encompasses the entire kingdom Animalia, a major group of multicellular eukaryotic organisms. Animal organisms are characterized by their heterotrophic nature, meaning they obtain nutrients by consuming other organisms, unlike plants which are autotrophic. They are also typically motile, at least at some stage of their life cycle, and reproduce sexually.

The animal kingdom is incredibly diverse, ranging from simple sponges and jellyfish to complex vertebrates like mammals, birds, reptiles, amphibians, and fish. These organisms exhibit a vast array of adaptations to their environments, from the microscopic to the colossal. Their life processes involve specialized tissues, organs, and organ systems that perform functions such as respiration, digestion, circulation, and reproduction. The study of animal organisms, known as zoology, explores their anatomy, physiology, behavior, evolution, and ecological roles. Understanding animal organisms is fundamental to comprehending biodiversity and the intricate web of life on Earth.
