Homeostasis in the Levels of Biological Organization

Our environment consists of various living and non-living components that play a big role in each of their corresponding field. Each and every component though serves different roles each and every one is mutually dependent on one another (Singha). Since these components are mutually dependent from one another, the biological organization would experience problems in more than one way (Singha). The levels of biological organization includes corresponding components that make up the whole biological organization, arranged from the smallest component to the largest component, each and every component serves their own importance in the whole biological organization.

The first level of the biological organization is the atoms. Atoms are described as the smallest unit of matter and is said to be the basic building blocks of matter (Singha). An atom consist three particles namely protons, neutrons and electrons (White). Protons contain positive electrical charges while neutrons do not contain any charge (White). With the combination of the positive charge of the proton and with the presence of a neutral neutron, when put together they form a positively charged nucleus in an atom (White). Most of the elements of an atom could be seen in the periodic table of elements. One example of atoms that our body needs is Oxygen. Oxygen constitutes about 65 of ones body weight (White). The function of oxygen in the human body could be found in both organic and inorganic compounds that are necessary for other chemical compounds (White). In order for atoms to achieve physical homeostasis, the atom emits excess energy, most commonly known as radiation, from the nucleus of the atom itself (New Jerusalem Network).

The second level of the biological organization is molecules. Molecules are formed when two atoms of the same element is united (White). One of the known molecules that could be found among humans is called Deoxyribonucleic Acid also known as DNA. Every nucleus of a living cell contains DNA, this molecule is said to have something to do with heredity (May). Each and every person has a unique DNA pattern, no two are alike, and this is why it is said that DNA could be used as a means of identification (May). At molecular level, homeostasis operates to regulate organic molecules production (Homeostasis of Molecules).

After atoms combine to form a molecule the next level the biological organization is the organelle. An organelle is a structure found inside a eukaryotic cell and its main function is to carry out specific functions to the specific cells (Wesolowski). Organelles are usually found in eukaryotic cells, that is why it is said that an organelle is the highest level of biological organization that is not considered living (Wesolowski). To maintain homeostasis in an organelle, organelles act within each cell and a one celled organism (Bein).

The fourth level of the biological organization is the cell. Cells are considered as the smallest unit of life and are often called the building blocks of life (White). The cell is the smallest level that is able to survive independently (Wesolowski). Cells are divided into two types prokaryotic and eukaryotic (Wesolowski). In homeostasis cells must makes sure to sustain a stable environment and cells must be able to reproduce by themselves whenever the body needs it (Homeostasis of Cells).

From atoms, to molecules, to organelles and cells, the fifth level of biological organization is the tissue. Tissues are made up of group of cells that could may or may not have the same characteristics (Singha). Tissues carry out particular function for a multi-cellular organism (Wesolowski). Homeostasis in tissues involves the preservation of balance within a specific tissue of an organism to control the proliferation of cells and the metabolic functions (Wesolowski).

The next level of the biological organization is the organ. Organs are formed when the different types of tissues are grouped together in an organized manner to form of what we know now as an organ (Singha). Some examples of organs that are made out of organized and grouped tissue are brain, lungs, kidneys, stomach, and many more (Singha). The organs in homeostasis do not over and under work because each organ assists the role of each organ (Beers).

After the organs comes the level of the organ system. The organ system is a group of organs that works together in order to carry out a bigger role particularly for multi-cellular organisms (Wesolowski). Since in organ system a group of organ is set to perform a specific task, each and every organ makes sure that to maintain homeostasis each and every organ should not underwork and overwork and that each organ would facilitate the functions of each other (Beers).

The last level of organization is the organism. An organism is said to be any form of life just like humans, animals, plants and many more (Singha). The term organism is said to be synonymous with life on Earth (Wesolowski). This is because what makes up an organism are all considered living. Homeostasis in organisms like humans, it should involve regular examination of facts including gases and other necessary substances (US Times Media). This goes to show that in order to meet the principle of homeostasis it involves all the previous levels of biological organization.

From the level of atoms to the level of organism it could be seen how each level is related to one another. This only proves that each level, though they may serve different and important functions, they still work side-by-side in completing the biological organization that would likely suffer when one level would be affected. .
