The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.
Q. What are the hierarchy levels of life?
The then describes life at the following levels; atom, molecule, macromolecule, organelle, cell, tissue, organ, organ system, organisms, population, community, ecosystem, biome and finally biosphere.

Q. What is the lowest level in the hierarchy of life?
A ? Living systems contain a hierarchy of levels that include, in ascending order of complexity, macromolecules, cells, organisms, populations, & species. Kingdom is the highest rank and species is the lowest rank in the hierarchy.
Q. What is the simplest level?
The simplest level is the chemical level, which includes tiny building blocks such as atoms. Cells are the smallest functional units of life. The simplest living creatures are single cell creatures, but in complex life forms, such as human beings, cells also exist in the tissue level.
Q. Are all cells alike yes or no?
Yes and no. Bacteria cells are similar to our cells in some ways. Like our cells, bacteria cells have DNA and a plasma membrane. But bacteria are unique in other ways….Prokaryotic Cells.
| Prokaryotic Cells | Eukaryotic Cells | |
|---|---|---|
| Membrane-Bound Organelles | No | Yes |
| Examples | Bacteria | Plants, animals, fungi |
Q. What can represent the simplest living thing?
bacteria
Q. Who discovered the cell?
Robert Hooke
Q. Who was first discovered bacteria?
Antoni van Leeuwenhoek
Q. Who found virus?
In 1892, Dmitri Ivanovsky used one of these filters to show that sap from a diseased tobacco plant remained infectious to healthy tobacco plants despite having been filtered. Martinus Beijerinck called the filtered, infectious substance a “virus” and this discovery is considered to be the beginning of virology.
Q. When was a virus first discovered?
Abstract. Two scientists contributed to the discovery of the first virus, Tobacco mosaic virus. Ivanoski reported in 1892 that extracts from infected leaves were still infectious after filtration through a Chamberland filter-candle. Bacteria are retained by such filters, a new world was discovered: filterable pathogens …
Q. What is the oldest known virus?
Smallpox
Q. How long does a pandemic last in 1918?
The influenza pandemic of 1918–19, also called the Spanish flu, lasted between one and two years. The pandemic occurred in three waves, though not simultaneously around the globe. In the Northern Hemisphere, the first wave originated in the spring of 1918, during World War I.
