- 1. LEVELS OF BIOLOGICAL ORGANIZATION IN AN ORGANISM There are distinctive materials in the environment. These are also diverse kinds of living and non – living things.
- 3. MOLECULES These are made of atoms, the smallest unit of chemical elements. They can be found in all living organism. Examples are H2O (water), N2 (Nitrogen gas).
- 4. CELL This is the basic unit and building block of life. Examples are human blood cells, plant and animal cell.

- 8. ORGAN SYSTEM Is a group of organs that work together to perform specific bodily functions. Examples: digestive system, circulatory system and other system in our body.
- 9. ORGANISMS Is a recognizable, self – contained individual. Organisms can be unicellular such as bacteria or amoeba, or multi – cellular composed of organs and organ system.
- 10. POPULATIONS Is a group of organisms of the same species occupying a given area. A colony of ants and herd of cows are examples of this.
- 11. COMMUNITY Is composed of all the population of different species of organisms living together in a given area.
- 12. ECOSYSTEM Is made up of all the communities in a certain area, as well as all the non – living physical components of the environment.
- 13. BIOSPHERE It is simply defined as the place, area, and zone where the entire life on Earth exists.
