Levels of organization are supposed to show us how the different levels relate with each another the complexity increase as we go from a basic something to something even bigger and greater. The cell is the basic unit of life. Life exists at the most fundamental level at the cellular level. The cell is the smallest anything can be considered alive. Then we have tissues where a bunch of cells come together to perform a specific function. Now if we combine a bunch of tissues together to perform a specific overall job, then we have an organ, so for example the heart is an organ. The heart doesn’t do its job by itself. The heart with the veins and the arteries and the capillaries and the blood. This all performs a big job for the body a system-wide job. This is called an organ system. So you get a bunch of organ system together and now we have an organism. An organism is a $10 word for critter. Cells are the basic unit of life. Going up from a cell. Bunch of cells coming together they perform the same function we have tissues. Those tissues come together to perform a job now we have an organ. Organs come together to do Big job that’s an organ system. Bunch of organ systems come together and they form the organism.
