What is the "biological hierarchy"?

Is it kingdom, phylum, class, order, family, genus, species? Or is it organelle; cell; tissue; organ; organism; species; community; population; ecosystem; biosphere?

Which one is it referring to?

The term "biological hierarchy" typically refers to the classification system used to organize and categorize living organisms based on their relationships and characteristics. There are two commonly recognized biological hierarchies: the Linnaean system and the ecological hierarchy.

The Linnaean system, also known as the taxonomic hierarchy, is the older and more traditional classification system. It involves the identification and categorization of organisms based on their shared characteristics. The hierarchy in this system is as follows: kingdom, phylum, class, order, family, genus, and species. This system primarily focuses on the morphological and anatomical features of organisms.

On the other hand, the ecological hierarchy views organisms within the context of their interactions and relationships with their environment. This hierarchy is as follows: organelle, cell, tissue, organ, organism, population, community, ecosystem, and biosphere. This system encompasses not only the biological components but also the physical and abiotic factors that influence living organisms.

So, depending on the context and the specific aspect of biology being discussed, the term "biological hierarchy" can refer to either the Linnaean taxonomic hierarchy (kingdom, phylum, class, order, family, genus, species) or the ecological hierarchy (organelle, cell, tissue, organ, organism, population, community, ecosystem, biosphere).
