How are living things organized? There are various levels of organization: and get bigger. Let’s start small

1) Atoms Atoms are the smallest unit of matter that have the chemical properties of a particular element. Examples: Carbon, Hydrogen, Oxygen…

2) Molecules Molecules that are the small building blocks from which larger molecules are made. Examples: Glucose Amino Acid Water

3) Macromolecules Large molecules consisting of many subunits. Examples: Protein Cellulose

4) Organelles Examples: Specialized structures inside of a cell. Mitochondria Cell Membrane

5) Cells Example: The smallest unit of biological organization that biologists consider alive.

6) Tissue A group of distinct and similar cells that carry out a specific set of functions. Examples: Muscle Skin

7) Organ Examples: Groups of tissues organized together to carry out a particular set of functions. Brain Stomach

8) Organ System Example: Groups of organs that function together to carry out broad sets of functions.

9) Organism (or individual) Examples: Individual that has its own distinct existence as a complex, reproducing unit.

10) Population Examples: Group of freely interacting and breeding individuals of the same species. School of fish Herd of Zebra

11) Community Example: Populations of different species living and interacting together in a distinct area. Marine community

12) Ecosystem Examples: Distinguishable groups of species and the abiotic (non-living) components of the environment with which the living creatures interact.

13.) Biome  Geographically defined area based on climate and environmental conditions.

14.) Biosphere  I’m sure you can figure this one out!
