Ecology and Grouping Organisms
Living organisms are classified into two main groups; plant kingdom and animal kingdom.
Animal kingdom is then sorted into vertebrates and in vertebrates.
vertebrates are animal with backbones.
invertebrates are animal without backbones.
vertebrates are sorted into five groups; Mammals, Reptiles, Amphibians, Birds and Fish
The bionomial system is used to name individual species.
Some organisms can be difficult to classify (e.g. Euglena, fungi)
Ecology and organisms
An ecosystem is where living organisms live in a habitat.
Ecosystems can be natural (e.g. ocean) and artificial (e.g. aquarium)
