Biotic factors

Back 4

A living component of a of a biological community;
an organism,
or an factor pertaining to one or more organisms

Front 5

Canopy

Back 5

Cover of dominant trees

EX: The canopy of the NW forests do not receive much sunlight

Front 6

Cell

Back 6

A basic unit of living matter separated from its environment by a plasma membrane;
the fundamental structure of human life

Front 7

Cohort of people

Back 7

all individuals within a particular age or class

Front 8

Community

Back 8

An assemblage of all the organisms living together and potentially interacting in a particular area
EX: all organisms on the california coast

Front 9

Deciduous

Back 9

Trees that lie dormant during the colder and darker winter months, and shed leaves during the autumn (because photosynthesis is not a priority in the winter months).

EX: Broad leaf biomes loose leaves annually every year in winter because not alot of light

Front 10

Dispersion pattern of a population

Back 10

refers to the way individuals are spaced within their area.

Front 11

Population density

Back 11

number of individuals of a species per unit area or volume --the number of oak trees per km2

Front 12

population

Back 12

a group of individuals of a single species that occupy the same general area.

Front 13

population ecology

Back 13

changes in population size and the factors that regulate populations over time.

Front 14

Discovery science

Back 14

verifiable observations and measurements are the data of discovery science.
uses inductive reasoning**
derives general principles from a large number of specific observations.

scientists observe and describe objects and phenomena,

"All organisms are made of cells."

Front 15

Dispersion patterns

Back 15

the way individuals are spaced within their area.
Random dispersion-not predictable
clumped-predictable
uniform-one individual per cell

Front 16

Disturbances

Back 16

storms, fire, floods, droughts, overgrazing, or human activity that damage biological communities, remove organisms from them, and alter the availability of resources.

Front 17

Ecological footprint

Back 17

an estimate of the amount of land required to provide the raw materials an individual or nation consumes, including food, fuel, water, housing, and waste disposal.

Front 18

Ecosystem

Back 18

consists of all the organisms in a community as well as the abiotic factors with which the organisms interact.

Front 19

Hypothesis based science

Back 19

testing of a hypothesis
make deductions
test predictions

Front 20

Keystone species

Back 20

species whose imapct on its community
is much larger than its biomass or abundance indicate
keystone collapses if removed from community.
**long spined sea urchin that corals depend on food..if removed, coral dies.

Front 21

Life tables

Back 21

track survivorship, the chance of an individual in a given population surviving to various ages.

Front 22

Mortality

Back 22

death rate of a population.

a growth rate of a population is affected by the birth rate and death rate.

Front 23

Molecule

Back 23

Two or more atoms held together by shared electrons (covalent bonds)

Front 24

Organ

Back 24

A structure consisting of several tissues adapted as a group to perform specific functions.
EX: Brain

Front 25

Organelle

Back 25

A membrane enclosed structure with a specialized function within a cell.
EX: Nucleus

Front 26

Organism

Back 26

an individual of a particular specices
EX: Brown Pelican

Front 27

Permafrost

Back 27

Continuously frozen ground found in the tundra.

Front 28

Primary consumers

Back 28

In the trophic structure of an ecosystem, an organism that eats plants or algae.

Front 29

Tissue

Back 29

a group of biological cells that perform a similar function
EX: Nervous tissue

Front 30

Secondary consumers

Back 30

gets its energy from other consumers
EX: Carnivores
The lion eats the jiraffe.

Front 31

Primary consumers

Back 31

Primary Consumer - an organism that gets its energy from producers (plants). These are often called herbivores.
EX: Jiraffe

Front 32

Primary producers

Back 32

Primary producers are plants because they must produce their own food to live and survive
EX: Algae

Front 33

Dominate Species

Back 33

one of a small number of species which dominate in an ecological community

Front 34

Survivorship

Back 34

the chance of an individual in a given population surviving to various ages.

Front 35

Survivorship curves

Back 35

plot survivorship as the proportion of individuals from an initial population that are alive at each age.

Front 36

Qualitative data

Back 36

A qualitative way to report room temperature would be to say "this room is warmer than it is outside".

Front 37

Quantitative data

Back 37

A quantitative way to report a particular room temperature would be "the temperature in this room is 23 degrees

Front 38

Name the three domains

Back 38

divides cellular life forms into archaea, bacteria, and eukaryote domains

Front 39

What is the difference between a prokaryotic cell and a eukaryotic cell?

Back 39

Prokaryotic cell--simpler and smaller than eukaryotic cell. -bacteria. It lacks a membrane enclosed nucleus and other membrane enclosed organelles. found only in domains bacteria and archaea.

Eukaryotic cell--has a membrane enclosed nucleus and membrane enclosed organelles. all organisms except bacteria and archaea are composed of eukaryotic cells.
