POPULATIONS AND ECOSYSTEMS. ORGANISM / INDIVIDUAL. Any living thing. ONE member of a species or population. EX: A deer, a rabbit, a bacteria, a tree, a flower, a mushroom, etc. POPULATION. A population is made up of all the organisms of the same species that live in an area at the same time.

ORGANISM / INDIVIDUAL • Any living thing. • ONE member of a species or population. • EX: A deer, a rabbit, a bacteria, a tree, a flower, a mushroom, etc.
POPULATION • A population is made up of all the organisms of the same species that live in an area at the same time. • EX: Bison living in the prairie, colony of fish, a pack of wolves, a grouping of trees
COMMUNITY • All of the different populations of all species LIVING in an ecosystem. • Only the populations living in an area, not the place where they live! • EX: Birds, deer, grass, trees, fungi, bacteria, ticks, all living together in the same area.
ECOSYSTEM • Consists of all the organisms living in an area, as well as the nonliving parts of that environment. • EX: Deer, birds, insects, grass, + the water, temperature, sunlight, soil, air quality, etc.
ABIOTIC • Nonliving things that effect living organisms. • EX: Sun, temperature, rainfall, soil
BIOTIC • Living organisms and products of living things.
BIOMES • A biome is a large geographical area of distinctive plant and animal groups. • The climate and geography of a region determines what type of biome exists. • 9 biomes Tundra, Deciduous Forest, Savanna, Taiga, Chaparral, Rainforest, Grasslands, Desert, Alpine. • Each biome consists of many ecosystems.
WHAT IS A SPECIES? • A class or group of individuals having similar characteristics. • Used to classify organisms. • How are organisms classified?
Taxonomy The science of classifying all living things into seven major groups based on similarities of structure or origin
Classification • How are organisms classified? • Kingdom • Phylum • Class • Order • Family • Genus • Species
Classification of Humans Animalia Chordata Mammalia Primates Hominidae Homo Sapien How do you remember the order? Kingdom- Phylum- Class- Order- Family- Genus- Species-
As you go down the column, the defining characteristics of each subgroup become more and more similar. The members of a kingdom are more diverse, and the members of a species are more similar.
If two organisms are in the same Order, they must be in the same Kingdom, Phylum, and Class.

Five Kingdoms • Monerans • Ex: Bacteria (single celled, prokaryotic) • Protista • Ex: Amoeba (single celled, eukaryotic) • Fungi • Ex: Mushroom (multicellular, eukaryotic) • Plantae • Ex: Flowering Plants (multicellular, eukaryotic) • Animalia • Ex: People, Elephants (multicellular, eukaryotic)
Binomial Nomenclature • Translates to “two-name name-calling” • Every species has a generic (genus) and a specific name (species) • Always in Latin • Carolus Linnaeus • Known as father of taxonomy • Made up the binomial system for naming organisms • Very similar to how people are named • Genus is the surname (last name) • Species is the personal name (first name)
Why use Scientific Names? • Many organisms have more than one common name • Many different species have the same common name • Ex: American Robin and European Robin • Universal language understood around the world
The Use of Scientific Names • Genus is always capital and species is always lower case • Underline the whole name • Examples • Felisdomesticus (house cat) • Canisfamiliaris (common dog) • Acersaccharum (maple tree)

Unusual Names Abracadabra (snail) Lacucaracha (moth) Wakiewakie (rat kangaroo) Bahumbugi (snail) Balbaroofangaroo (kangaroo) Chaoschaos (protozoan) • http://www.acsu.buffalo.edu/~insrisg/nature/nw98/names.html
What is your Scientific Name? - a persons name - last name first (genus) - first name is lower case (species) • add proper endings and underline Now write your name! For Example: Bart Simpson Simpson Bart Simpson bart Simpsonusbarti
LINNAEUS • Swedish botanist • Born in 1700’s • Made up the binomial system for naming organisms • Known as father of taxonomy
How are organisms classified? Animalia • Kingdom- Phylum- Class- Order- Family- Genus- Species- Chordata Mammalia Primates Hominidae Homo sapiens
Acronym to remember • Kings Play Cards On Fat Green Stools • King Phillip came over for good supper • Make up your own
Binomial Nomenclature • Translates to “two-name name-calling” • Every species has a generic (genus) and specific name (species) • Always in Latin • Very similar to how people are named • Genus is the surname (last name) • Species is the personal name (first name)
Why use Scientific Names? • Many organisms have more than one common name • Many different species have the same common names • American Robin and the European Robin • Universally understood throughout the world
How does it work? • Genus is always capital and species is always lower case • Examples of scientific names: • Felis domesticus (house cat) • Canis familiaris(common dog) • Acer saccharum(maple tree) • Satter kari
Weird Scientific Names • Abracadabra (snail) • Lacucaracha (moth) • Wakiewakie (rat kangaroo) • Bahumbugi (snail) • Balbaroofangaroo (kangaroo) • Chaoschaos (protozoan) • http://www.acsu.buffalo.edu/~insrisg/nature/nw98/names.html
How to “latinize” your name For example: Bart Simpson -a person’s name Simpson Bart - last name (genus) first Simpson bart -first name is lower case (species) Simpsonus barti -add male endings to genus and species
TAXONOMYpages 8 and 9 Science of classifying all living things into seven major categories
Which group on the chart do you think has the most organisms in it? • Kingdom
What are the five kingdoms? • Monerans • Protista • Fungi • Plantae • Animalia
1. What do all animals have in common? • Heterotrophic • Eukaryotic • Multicellular
What four organisms are put in the same first three levels? • Human • Chimp • House cat • Lion
3. What do you notice about the characteristics of the groups as you move down the Animalia kingdom? • They become more similar
3. Compare the characteristics of a kingdom verses a species. What do you notice? • Kingdom is more diverse • Species is more similar
Are the cat and housefly the same species? • NO, because the groups above them don’t all match. • Species is like a first name it means little unless the last name (genus) is with it.
4. If two organisms are in the same Order, they must be in the same… • Kingdom • Phylum • Class
5. Every organism is given a scientific name that consists of what? • Genus • Species • Which one is always capitalized? • Which one is always lower case?
7. Which two organisms are most closely related on the chart? WHY • Cat and lion • They are the same in 6 of the 7 levels of classification.
7. A human is most closely related to what organism on the chart? WHY • Chimp • They are the same in 4 of the 7 levels of classification.
