rain with an acidic Ph caused by burning fossil fuels...destroys life in lakes/rivers

self-feeder; any organism that carries out photosynthesis...a producer

a decomposer that helps to break down dead material and recycle it

having a wide variety of organisms living in an ecosystem. Biodiversity builds the stability of an ecosystem.

the largest number of organisms in a population that an environment can support

fight to obtain food, shelter and mates

an organism that must eat another organism

an organism (bacteria & fungi) that break down dead material and recycle it.

the cutting down of trees to make room for buildings or grazing land.

the study of the interaction between organisms and their environment

all the organisms that live in an environment with their non-living environment

the amount of enery available decreases as you move up the food chain.

when all organisms of a particular species are dead

all the possible interactions among the various organisms in an ecosystem (who eats who)

coal, oil and gas...non-renewable resources that cause damage to the environment when burned

help the ecosystem by working as decomposers

increase in earth's temperature as a result of an increase in carbon dioxide in the atmosphere

an organisms that consumes another organism to obtain energy

the use of factories, etc. to increase human comfort and convenience

the factors that prevent a population from growing out of control (space, food, predators, etc.)

the layer of 03 in the atmosphere that protects Earth from ultraviolet rays

a symbiotic relationship where the parasite hurts the host (lice, tick, etc.)

placing harmful materials into the biosphere

the general pattern of growth of an organism. they start by increasing quickly, but then level off at the carrying capacity.

relationship between organisms where one eats the other

a plant; something that uses photosynthesis to make its own food; autotroph

to break down used material into something that is usable again.

something that eats dead organisms

The most stable community that a climate can support. It is the most biodiverse and will remain unless acted upon by weather or man.

Species living in an area where they did not originate. They have no predators and therefore outcompete the native species reducing biodiversity.

energy pyramid	the amount of enery available decreases as you move up the food chain.
extinction	when all organisms of a particular species are dead
food web	all the possible interactions among the various organisms in an ecosystem (who eats who)
fossil fuels	coal, oil and gas...non-renewable resources that cause damage to the environment when burned
fungi	help the ecosystem by working as decomposers
global warming	increase in earth's temperature as a result of an increase in carbon dioxide in the atmosphere
herbivore	an organism that eats plants
heterotroph	an organisms that consumes another organism to obtain energy
industrialization	the use of factories, etc. to increase human comfort and convenience
limiting factors	the factors that prevent a population from growing out of control (space, food, predators, etc.)
ozone layer	the layer of 03 in the atmosphere that protects Earth from ultraviolet rays
parasite/host	a symbiotic relationship where the parasite hurts the host (lice, tick, etc.)
pollution	placing harmful materials into the biosphere
population growth	the general pattern of growth of an organism. they start by increasing quickly, but then level off at the carrying capacity.
