- Sub-divided into smaller groups. Organisms with common features
- Plants
- Kingdom Phylum Class Order Family Genus Species
- Animals
- Vertabrates
- Fish Amphibians reptiles birds mammals
- Split into classes based on....
- How they absorb oxygen (lungs, gills etc)
- How the reproduce- Oviparous (lay eggs) Viviparous (live birth)
- How they regulate body temperature- Homeotherm ( constant tempertaure0 Poikiotherm( changes with external heat.
- Split into classes based on....
- Fish Amphibians reptiles birds mammals
- Invertabrates
- Vertabrates
- Organisms are the same species if the can interbreed to produce fertile offspring
- However some species produce asexually
- If two different species breed and produce offspring then this is called a hybrid. (e.g. Mallard with a yellow billed duck)
- There is a lot of variation within a species. E.g. there are tons of breeds of dogs.
- A ring species is a group of related populations that live in neighbouring areas.
- Populations living next to each other can interbreed and produce fertile offspring. Ones that live further apart can't.
- The binomial system gives each species a two part Latin name.
- It helps scientist- identify species, study species conserve species and target conservation efforts.
- A key is a series of questions that can be used to identify an unknown organism.
