  2. Tissues
  3. Organs
  4. Organ Systems
  5. Organism

Explanation:

Five Levels of Organization:

Cells:

Cells are the fundamental levels of organization of living organisms. They are the basic structural and functional units of life. Cells are composed of different organelles that perform various functions and through division of labor, accomplish different cellular tasks. E.g, muscle cell, neuron (nervous system cells), nephron (specialized kidney cells) etc.

Tissues:

Cells that perform similar functions combine together to form tissues. For example, skeletal muscle tissue, cardiac muscle, vascular tissue etc.

Organs:

Organs are complex structures formed by the combination pf two or more types of tissues that perform specific but related functions. E.g, heart (pumps blood, contains cardiac muscle tissue), brain (conducts nerve impulses, contains neural tissue).

Organ Systems:

Organ systems are a combination of organs that perform related functions and work together to perform specific physiological functions. E.g, circulatory system (contains heart and circulatory system).

Organism:

This is the highest level of organization. An organism is a combination of cells, tissues, organs and organ systems that all work together to perform specific physiological functions.

What is representative organism?
Ann [662]

First off, know that the whole division into kingdoms idea has been removed. All living creatures are now separated into domains: Bacteria, Archaea, and Eukarya. Still, I can provide a few for each category.  

Monera is all the bacteria and archae bacteria in the world. They are all prokaryotes and therefore have no nucleus. Some examples are the certain diseases, such as Streptococcus pneumoniae (the bacteria that causes pneumonia) and Micobacterium tuberculosis (which causes tuberculosis).  

Fungi are all the fungi of the world, all of which are eukaryotes that exist in both diploid and haploid stages. They include all the mushrooms of the world and molds like the bread mold, Rhizopus stolonifer.  

Protists are extremely diverse, many being eukaryotes, though some are prokaryotes, and some being unicellular while others and multicellular. They are divided into three categories, protists (animal-like), which include Amoeba, algae (plant-like), which include Ulva, and fungus-like, which include chytrids.
