Eluorganismide

Eluorganismide (Estonian for living organisms) are entities that exhibit the characteristic properties of life. They are organized systems capable of metabolism, growth, development, reproduction, response to stimuli, and homeostasis. They range from single-celled microorganisms to large multicellular plants and animals. Most show genetic information encoded in nucleic acids and rely on cellular membranes to separate internal from external environments. While the metabolic diversity of eluorganismide is vast, they share a common ancestry and adapt to diverse habitats.

Biologists classify life using a hierarchical framework that reflects evolutionary relationships. A widely used scheme divides life into three domains: Bacteria, Archaea, and Eukarya. Within Eukarya are the kingdoms Protista, Fungi, Plantae, and Animalia, among others. Organisms can be prokaryotic (lacking a nucleus) or eukaryotic (with a nucleus and organelles). The study of eluorganismide spans microbiology, physiology, ecology, and evolutionary biology.

Reproduction occurs through asexual and/or sexual means, enabling genetic variation and adaptation. Evolution explains how populations of eluorganismide change over generations in response to environmental pressures. In ecosystems, living organisms participate in energy flow and nutrient cycling, forming networks that sustain habitats.

A minority of researchers argue about whether viruses should be counted among eluorganismide, since many require hosts for replication and lack independent metabolism. Overall, the study of eluorganismide seeks to understand the diversity, functions, and history of life on Earth.
