Organsim

Population

biomes

tundra

desert

rainforest

temperate deciduous forest

coniferous forest

freshwater biome

marine biome

grassland/savannah

food chain

producer

primary consumer

tertiary consumer

decomposer

food web

many organsims and biotic factors can be connected and the transfer of energy can go to many differnt organisms

biodiversity

genetic

species

ecosystem

endangerd species

a species that will soon die out if we do not change the thing we are doing to harm them

threatend species

not as bad as and endangerd species but but the species is at risk of being endangerd

biotic

Something that is living, was living or peices of a living thing.

abiotic

hot spot

community

Ecosystem

Trophic levels

Biome

Indicator species

Indicates when a ecosystem is not healthy

ecological succession

primary succession

secondary succession

pioneer species

climax community

limiting factors

limiting factors help keep our population under controll

carrying capacity

how much of a species an ecosystem can hold

population growth

how many people are in the population

population growth rate

how fast a population grows

exponential growth

total ammount of growth

J-curve

a regular good population growth this is what the human population is following

S-curve

starts out as a J-curve but then when carrying capacity is reached the population starts to go down

Water pollution

non-point source

point source

aquifer

most of our accesable freshwater comes from aquifers which are underground sources of water

desalination

water purification

when polluted water is cleanded, a large ammount of the world lives without purified water

Watershed

a place where runoff water drains to when it rains. There are 4 big watersheds in Pensylvania alone.

impermeable

an impermeable surface does not absorbe water

an impermeable surface could be concrete , blacktop, or other surfaces that do not absorbe water

runoff water

runoff water ussullay caries many non-point source pollutants that end up in our watersheds

wetlands

where aquatic life lives, this is a water based ecosystem

urbanization

Organic pollutant

inorganic pollutant

natural resource

nonrenewable resource

oil

coal

gas
