Applied ecology Flashcards
changes driven by human activities like fossil fuel burning which increases heat dropping greenhouse gas levels in Earth’s atmosphere racing Earth’s average surface temperature commonly referred to as
global warming
organic mother is needed in the aquatic party you chemical cycle however this too in excess causes of refertilization and can trigger the chain of events
eutrophication
the latters die off brings about an _____ since it further consumes more of the oxygen
anoxic condition
effects of climate change
- melting of polar caps
- sea level rise
- increase precipitation
- severe drought
- spread of diseases
- changes in the ecological systems
can soon dominate the environment because they do not have predators to keep them in check
when species are aggressive
are capable of crossing extinctions of native plants and animals
invasive species
organisms that are alien to a certain environment
exotic species
The complex alterations in the weather and climate systems of the planet Earth
climate change
greenhouse gases that observe the radiation reflected by the Earth hence blocking the heat which is supposed to release in the atmosphere
methane ammonia sulfur dioxide ozone and water vapor
when applied in excess of what is needed or when it is not needed The superfluous nutrients join the water table or run off the land and eventually reach water bodies
euthropication
wise among the elderly
leaders
it is created so that extreme conditions are livable
artificial environments
handmade of industrialization
fuel
initial fuel
wood
sources of power
fossil fuels hydropower geothermal power nuclear power
coal natural gas peat petroleum
fossil fuels
water from dams
hydropower
energy from steam
geothermal power
results from fission or split of uranium or plutonium atoms
nuclear power
distribution of power in a society
politics
system by which goods and services are exchange
economics
worldviews the cheap and are shaped by human culture
value systems
first technological stage
human gathering or paleolithic
a determinant of how natural resources and impacts on the environment are valued and utilize
worldview
two predominant subsystems
economic political
bigger than the carrying capacity
the population crashes
high yield hybrids
The green evolution
jeans have been altered through genetic engineering
genetic engineering and GMOs
from with or other carbonaceous materials
biomass
methane
biogas
difference in temperature between the surface water and lower layers of the ocean
ocean thermal energy conversion
reaction of hydrogen and oxygen releases energy
hydrogen
it increase crop yields
chemical fertilizers
scientific knowledge translated into practical purposes
technology
not capable of large scale changes in landscape destruction of ecosystems nor pollution of water in the air
low technology low numbers
threats to biodiversity have to be addressed through various strategies
legislation and land use planning information and education
wide variety of life on Earth
biodiversity
provision for basic needs
utility value
Knowing that it is there to be used
hidden wealth
natural biological evolution based on species being replaced extremely gradually by those who are better adopted to changes environment
extinction
going beyond essentials of leaving
extracting too much
development that meet the needs of the present generation without compromising The ability of future generation to meet theirs
sustainable development
reasons for extinction
- loss of habitat
- modern agricultural practices
- cultivar selection
- over harvesting
- introduction of exotic species
- global warming
- chemical and heavy metals
The disposed product of a once useful system
waste
harmful waste
pollution
destroy ecological balance when they went to this exceed a certain threshold level
ecologically dangerous substances
related to cancer, interface with the conduction of nerve impulses
Dichloro-diphenyl-trichloethane DDT
synthesized from the combination of organic molecules and chlorine
dioxins and furans
makes up the major portion of Earth’s surface
water
drives all phenomena in nature
hydrologic cycle
dangerous through long-term exposure
hazardous substances
The process of undesirable substances or of certain substances over some threshold level in our lives of our systems
pollution
boy something to human health even in minute quantities
toxic substances
such as pesticides insecticides herbicides fungicides which interfere with the natural physiology
persistent organic pollutants POPs
The presence of any substance in air water soil or food which threatens the health of human animal and plant life
pollution
resulting to salinity
SeaWater intrusion
single large emitter into the environment means source can be traced back at
point sources
hard or even impossible to trace back because their pollutants are dispersed
non point sources
running water
lotic
freshwater or sea water
lentic
define by how they resolve the three basic economic questions of what goods should be produced how they should be produced and for whom they should be produced
economic system
