BIO

In this discussion you are to describe and discuss "levels of organization in biology." Higher biological organisms are organized from different organ systems, and these are made up of specific organs, which in turn are made up of specific cells, etc.

For a eukaryotic organism of class mammalia (a mammal), how many levels can you identify (hint, start at the level of atoms, and work up from there). Do the levels stop at the level of an "organism?" Go as far as you can past the level of "organism." The deadline for conference participation is 11:59 pm, 3 November. Remember to cite a reference for the authoritative source you use to provide the information in your post and complete two substantial response posts

Every living thing is made up of highly organized and complex structures. There may be some differences when it comes to what animals and plants are made up of, but the structure remains similar. From atoms that we cannot see with the naked eye to humans, plants, and animals that we see every day, these organisms each have their levels of organizations. Levels of organization are arranged from the simplest to the most complex. In this topic, I will discuss the levels of organization of mammals.

There are many levels of organization in the structure of mammals such as humans. Each level has their own components. To start from the smallest, there are molecules. Molecules are made up of atoms. When atoms combine, they form a cell. “A cell is the basic unit of life.” (Yearout, 2019) When cells work together, they form tissues such as our skin tissues. Think about when you get a cut, how does the cut heal? We cannot see it with the naked eye, but at the microscopic level, blood cells are working together and in time the cut closes and new skin is formed. When tissues work together on a much larger scale, they form organs. Organs such as the heart, lungs, and liver are important to keep the human body functioning properly. After that there is the organ system. The organ system is when different organs “work together to perform specific bodily functions.” (Yearout, 2019) The digestive system for example, digests food and nutrients are absorbed into the body. The digestive system includes the esophagus, liver, intestines, and stomach. Put all these together and you get an organism. A dog, a cat, a cow, humans are all examples of an organism, something easily recognizable.

For the class of mammals, it does not stop at the level of organisms. There is the population, community, ecosystem, and lastly the biosphere. The biosphere is all these put together and includes every plant, animals, and molecules. As we get to the level of biosphere, the grouping becomes larger and more diverse.
