Ecosystem
Why do organisms interact with their environment?
organisms interact to meet their needs for food to survive. Food is their energy they need to survive.
Primary producers
Organisms that make their own energy (food). trophic levels 1
Carbon dioxide(co2)
Greenhouses gas, waste product of combustion & decompostion
climates zones
Tropical, temperate, polar
What are the properties and dangers of water pollutants?
Where does water pollution come from? - What are the specific ways through which water pollutants enter the environment? - How are pollutants transported through water?
in my neighborhood, every Tuesday the garbage man comes to take away the trash. which organisms take away the trash in the desert ecosystem?
Decomposers take away the trash on all ecosystems. in a desert ecosystem, vultures and ants are decomposers. we have vultures and ants where we live too.
Primary Consumer
Organisms that eat producers.
Fossil fuels
formed from the decomposition of long-ago living organisms
greenhouse effect
Natural situation in which heat is retained in eath's atmosphere by carbon dioxide, methane,water vapor, and other gassws
wastewater
water produced by livingstock, human sewage and gray water from bathing and washing of clothes and dishes
is the sun important?
The sun is very important without the sun, plants would not grow, weather would not occur, our planet would not be warm.
Secondary consumer
Organisms that eat primary consumers
greenhouses effect
the sun's energy enters but infrared energy is trapped
Climate change
Any significant change in measures of climate, such as temperature, precipitation, or wind, lasting for an extended period of a decade or longer
point source pollution
pollution that comes from specific site
Ecoyosystem are complex. What features must an ecosystem have to be balanced?
Ecosystems must have both biotic and abiotic components. There must be enough producers to support the consumers. we need all kinds of consumers to balance each other out.
Tertiary consumer
Organisms that eat secondary consumers.
greenhouses gases
heat rapping gases in earth's atmosphere
Carbon dioxide
(CO2) sources include the combustion of fossil fuels. Effects: greenhouse gas contributes to global warming. reduction accomplished by increased fuel efficiency (gas mileage), mass transit
reservoir
a large natural or artificial lake used a a source of water supply.
Are nonliving components of an ecosystem important?
Non living components are very important. air is nonliving. Air contains oxygen which organisms need to breath to live. Air also contains carbon dioxide. Plants need carbon dioxide to produce their food. Animals need the sun for the heat it provides.
Trophic levels
An organism's position in a food web. It is based on food/feeding
global climate change
variation in the long term temperature of the earth
Recycling
Convert waste into reusable material.
aquifer
an underground layer of water bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or slit) from which groundwater can be extracted using a water well
