Biological Levels of Organization
- Atom: the building block of matter, making up all material in the universe
- Molecule: a group of atoms, including macromolecules like carbohydrates, proteins, nucleic acids, and lipids
- Cell organelles: components that make up cells
- Cell: the basic structural and functional unit of life
- Tissue: a group of similar cells
- Organ: a group of tissues that perform a specific function
- System of organs: a group of organs that work together to maintain homeostasis
- Organism: an individual living thing
- Population: a group of the same species living in the same geographical area
- Community/Biocenoses: a group of different species living together
- Ecosystem: the interaction between organisms and their environment
- Bioma: a region classified based on the species that inhabit it
Branches of Biology
