arrows show the energy flow

biotic and abiotic factors

Biotic- a living or once living organism

paper, pig, tree

Abiotic- a non-living organism

clock, cloud

organism

ecosystem

an area in which different organisms live

population

a goup of the same organism living together

a bunch of mice

2

community

different organisms co-existing

mice and chipmunks

Biodiversity

The variety of organisms in a geographic area

Genetic Bodiversity

species biodiversity

Problem: humans are killing organisms faster then they can reproduce

Ecosystem biodiversity

Hot spot

endangered species

in danger of extinction thoughout most of the area or all of the area it inhabits

threatened species

is likely to become endangered int the near future

Indicator species

New node

ecological succesion

J-curve

it shows the growth of population

Population Growth rate

the speed at which the population growth over a certain amount of time

S-curve

it show the growth of popuation

Population growth

the change in population over time

Ecological succession

Primary succession

when a piece of land grows vegetation but has never had any life on it before ex: a volcano erupts and creates a new island

ex of ecological succession

Secondary succession

when a piece of land grow vegetation after it was once destoid ex: a fire wipes out all living things but eventualy grows back

Pioneer species

they are the first species to start on a new land or area to live

climax community

when the vegetation eventualy reaches a steady rate

limiting factors

something that controls the growth of organisms, Ex- space,disease,ect.

Carrying capacity

when a place has so many people/organisms that the space and resources cant support them

runoff

A water flow that goes down the storm drain colecting excess soil, debris, and all kinds of litter ect.

water polution

causes-sewer discharge, poorly managed livestock, detergents, petroleum products ect.

aquifier

a water purifier

desalination

the remove of excess salt or other unwanted substances from water

water purification

the process of removing unwanted substances from raw water

watershed

it seperates the drainage system stuff

Impermeable

a serfice that water cant go through. such as cement, in a parking lot ect.

erosion

a gravity driven process that moves sediments (ect.)

wetlands

examples: bog, marsh, or swamp
