Environmental Science
inorganic pollution
Inorganic chemical pollutants are naturally found in the environment but due
to human development these pollutants are often concentrated and released
into the environment in urban stormwater. The primary inorganic pollutants of
concern in urban stormwater are cadmium, copper, lead, zinc, nitrogen,
nitrate, nitrite, ammonia, phosphorous, and phosphate.
natural resource
a natural resource is something that is used
that comes from a natrual source like usn,
wind,ect.
Renewable Source
an example of a renable source is iwnd energy
and solar panels and shingles that collect energy
from the sun
Nonrenewable source
a nonrenewable source is sometihng that cant
be recycled or reused. it will probably end up
in a dump collection area
Limiting Factors
these are things in an ecosytem
that tell whether its growing
healthy
Exponential Growth
the maximum, equilibrium number of
organisms of a particular species that can
be supported indefinitely in a given
environment.
J Curve
a curve in te gragh that starts
out level and goes up making a j
shape
S Curve
this is when a line gragh makes the
form of an S, leveling off at the
end.
Biodiversity
it is the variety of life on earth
for example many different
things creating lots of
diversity
Trophic Levels
any class of organisms that occupy the same
position in a food chain, as primary
consumers, secondary consumers, and
tertiary consumers.
Decomposer
an organism, usually a bacterium or
fungus, that breaks down the cells of dead
plants and animals into simpler substances.
Tertiary consumer
a carnivore at the topmost level in a food
chain that feeds on other carnivores; an
animal that feeds only on secondary
consumers.
Aboitic Factors
They are things that arent
living and never living
Example: Rock,sand,steel
Biotic Factors
They are things in life that
are living or once were living
Secondary consumer
a consumer that gets its energy from other
consumers. These are often called
carnivores.
Primary Consumer
an organism that gets its energy from
producers (plants). These are often called
herbivores.
Producer
Example
Food web
A complex of interrelated food
chains in an ecological
community
Food Chain
A food chain shows how
each living thing gets its
food
grassland/savannah
This biome is a highly seasonal
environment of temperate
regions.
Marine Biome
Marine regions cover about threefourths
of the Earth's surface and include oceans,
coral reefs, and estuaries.
Freshwater Biome
The Freshwater Biome accounts for one fifth of the area
of the Earth and provides half of the drinking water, one
third of the water used for irrigation, and nearly ninety
percent of the world's bathwater.
Tundra
one of the vast, nearly level, treeless
plains of the arctic regions of Europe, Asia,
and North America
Coniferous Forest
a type of forest characterized by
conebearing, needleleaved
trees
Temperate deciduous forest
The temperate deciduous forest
is a biome that is always
changing.
Ecosystem
a system formed by the interaction of a
community of organisms with their
environment.
Community
an assemblage of interacting
populations occupying a given
area
Population
the assemblage of a specific
type of organism living in a given
area.
Organism
a form of life composed of mutually
interdependent parts that maintain
various vital processes
food chain
the food chain is the way energy flows from
one thing to another; otherwise who gets
the energy and how it comes from the sun
desert
Snakes
lizards
rabbits
very hottt!!!
rainforest
the rain forest has alot of heavy rain fall
and its very humid. lots of different
species.
Biomes
biomes are areas in which
ecosytems exist
