|Biodiversity & Classification||Biodiversiy is the variety of life in the world or in a particular habitat or ecosystem. Classification is the division of organisms into kingdoms, groups, or classes based on specific characteristics.|
|Purpose of Classification||Classifying answers questions such as:
-How many known species are there?
-What are the defining characteristics of each species?
-What are the relationships between these species?
|Taxonomy & Founder|| Taxonomy is the science of naming, describing, and classifying organisms.
Carolus Linnaeus founded modern taxonomy and classified all living things based on their structure.
|Seven Levels System|| The Seven Levels System is a classification system based on shared characteristics
Kingdom, Phylum, Class, Order, Family, Genus, Species
The more characteristics the organisms share, the more closely related they might be.
|Vertebrates||Vertebrates have a backbone and spinal column. They can be divided into further groups:
fish, amphibians, reptiles, birds, and mammals.
|Dichotomous Key||A Dichotomous Key is an aid used to identify organisms and that consists of the answers to a series of questions.|
|Scientific Name||A scientific name is made up of the Genus and Species. The Genus name begins with a capital letter, and the Species name starts with a lowercase letter.|
|Animals||Animals are multi-cellular, can usually move, depend on other organisms for food, and undergo sexual reproduction.|
|Intervertebrates||Intervertebrates don't have any type of bones, including backbones, but have an exoskelton for support.|
|Mollusks||Mollusks have a hard shell to protect soft parts of their bodies and a muscular foot for movement. Ex: clams, slugs squids, octopus|
|Arthropods||Arthropods have exoskeletons, a segmented body, and jointed legs. Ex: lobsters, crabs, insects, and spiders|
