Jacki's Enviormental Science Mind Map

Organism

single living unit

Population

a group of the same organism living together

Community

different types of organisms living together

Ecosystem

biotic and abiotic things living together

Biomes

area in which the ecosystem exsists (climate, location, region)

Rainforest

a tropical forest mostly of tall, closely-growing trees in an area with a large annual rainfall

Temperate Deciduous Forest

PA is in this biome

Coniferous Forest

cone-bearing, needle-treed forest

Desert

little to no rainfall

Tundra

treeless plains

Freshwater Biome

a biome in which the water usually contains less than 1% of salt

Marine Biome

any biome of water

Grassland/Savannah

an area, such as a prairie, in a semiarid climate

Food Chain

organisms related in feeding habits

Food Web

interrelated food chains in an ecosystem

Producer

an organism that can produce its own food from inorganic substances

Primary Consumer

an herbivore

Secondary Consumer

a carnivore that feeds on herbivores

Tertiary Consumer

a carnivore that feeds on other carnivores (secondary consumers)

Decomposer

breaks down dead cells into simplar substances

Trophic Levels

organisms that occupy the same postion in a food chain

Biotic Factors

things that were, or once were, living

Abitotic Factors

things that never lived

Biodiversity

variety of organisms living together in a geographic area

Genetic Biodiversity

differences in individuals of the same species

Species Biodversity

variety of a species in a given area

Ecosystem Biodiversity

communities linked together as an ecosystem

Hot Spots

17 regions where more than half of all species are found

Endangered Species

species in danger of extinction

Threatened Species

likely to become endangered

Indicator Species

species whose presense, absense, or well-being is indictive to the health of an ecosystem

Ecological Succession

process in which communities change over time

Primary Succession

development of life in a place where no ecosystem previously existed

Secondary Succession

development of life in a place where life has previously exisisted

Pioneer Species

the first species to colonize previously uncolonized land

Climax Community

an ecosystem where populations can exsist stabily and in balance with one another

Limiting Factors

factors that limit the growth of a species

Carrying Capacity

the amount of organisms an ecosystem can hold without depleating its resources

Population Growth Rate

the number of people a population grows by in a certain length of time

Population Growth

increase in population

Exponential Growth

development at an extremely rapid rate

J-Curve

a curve that graphs exponetaial growth

S-Curve

a curve that graphs exponetial growth, and then the leveling out that occurs

Water Pollution

any unnatural substance that is added to water, making the water harmful to life

Aquifer

geological formation that contains or conducts water

Desalination

the removal of salt from something

Water Purification

removing harmful substances from water

Watershed

all waste water from a certain area will drain into the same place

Impermeable

unable to absorb water

Erosion

process in which the surface of the earth is worn down

Runoff

water that flows from land to streams

Wetlands

land that is wet

Urbanization

process in which cities grow

Point Source

where it is possible to determine the orgin of pollution

Nonpoint Source

where pollution has combined so that the location of orgin cannot be detirmined

Organic Pollutant

compounds that are resistant to enviormental degradation

Inorganic Pollutant

natural pollutants that are concentrated by human development

Natural Resources

resources that are not manmade

Renewable Resources

Nonrenewable Resources

resources that exist in a limited supply
