DIVERSITY OF LIVING THINGS. Organization of Organisms. Diversity. The vast diversity of living things is astounding! Biologists study differences between organisms in order to classify them Diversity within species is important to the species survival
Organization of Organisms
Example: genus species
Canis familiaris (dog!)
Often instead of repeating the genus we used the initial
Example: Escherichia coli becomes E coli
Please note the genus is always capitalized and the species is NOT.
King Philip Came Over For Good Spaghetti
Kingdom Broadest level
Species Most Specific level
Think of the classification system as an upside down pyramid. The Kingdom is the largest part and can hold the greatest number of organisms such as all the animals or all the plants.
As you move down the pyramid each level or ‘room’ gets smaller; it can hold fewer and fewer organisms. However, the members have more traits in common and begin to look alike.
The species is the smallest ‘room’ in the classification system and is only large enough for one kind of organism – only humans, only houseflies, etc.
