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.

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.

BIOMESA 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?

The science of classifying all living things into seven major groups based on similarities of structure or origin

How are organisms classified? Kingdom Phylum Class Order Family Genus Species

Homo

Sapien

How do you remember the order?

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.

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)

Many organisms have more than one common nameMany different species have the same common name Ex: American Robin and

European Robin

Universal language understood around the world

Genus is always capital and species is always lower caseUnderline the whole nameExamples

Felis domesticus (house cat)Canis familiaris (common dog)Acer saccharum (maple tree)

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?

MoneransProtistaFungiPlantaeAnimalia

1. What do all animals have in common?

HeterotrophicEukaryoticMulticellular

What four organisms are put in the same first three levels?

HumanChimpHouse catLion

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 diverseSpecies 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…

KingdomPhylumClass

5. Every organism is given a scientific name that consists of what?

GenusSpeciesWhich one is always capitalized?Which one is always lower case?

7. Which two organisms are most closely related on the chart? WHY

Cat and lionThey 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

ChimpThey are the same in 4 of the 7 levels of classification.
