Taxonomy is the naming and classifying of organisms. A taxon is a group of organisms in a classification system.
Key concept:
The current tree of life has three domains (Bacteria, Archaea, Eukarya)
- All living things bear scientific names that use the binomial signature (two parts, reflecting its genus and species)
- Linnaeus Classification System: Seven levels (need to remember all seven: Kingdom, Phylum, Class, Order, Family, Genus, Species)
- Linnaeus taxonomy does not account for molecular evidence
- Interpret data given from this classification system
- There are six kingdoms (Animalia, Plantae, Protista, Archaea, Bacteria, Fungi) and preceding that, 3 domains
- Domain Bacteria branches into the Bacteria kingdom
- Domain Archaea branches into the Archaeal kingdom
- Domain Eukarya (all eukaryotes) branches into the Protista, Animalia, Plantae and Fungi kingdoms
- Classification of living things is a work in progress.
And a little bit on ecology:
- Living things cannot exist alone, there must be a relationship between them.
- Living things are adapted to the environment where they live.- Ecology is the study of how living things interact with each other and with their environment.
- Abiotic factors (light, temperature, water) & biotic factors (organisms)
