SCIENCE 8 GRADE: Living Beings Organization

THE LIVING BEINGS ORGANIZATION

The organization of living things can be seen like a pyramid or tree with seven major levels or categories: Kingdom, Phylum, Class, Order, Family, Genus, Species.

There is a simple pneumonic that can help students remember the organization of nature, for example the Human:

The Animal …Kingdom, sharing with all other members of this group the need to feed on organic matter (unlike plants which can create energy using light and minerals)


The Chordate (or vertebrate) … Phylum, sharing with all other members of this group of animals, a back bone with a hollow nerve chord

The Mammal … Classsharing, with all other members of this group of vertebrates, the ability to feed their offspring on milk and having a body covering which includes fur

The Primate … OrderSharing, with all other members of this group of mammals, a thumb that can be opposed to the other digits, binocular vision and various more broadly defined characteristics (including high intelligence, relatively long maturation period for the young, dental similarities, tendency for complex social organization, and generally bearing one or two young).
