Deforestation
Removing carnivores from a forest
Recycling
Heating homes with fossil fuels
Approximately 75 percent of the Earth's surface is covered in water. Why is water considered such a precious resource?
The interaction of sunlight with pollutants produced by fossil fuels
What affect does logging have on the forest ecosystem?
When certain chemicals such as CFC (chlorofluorocarbons) react with Ozone (O3), ozone breaks down to O2 (oxygen gas). Why would this have a negative impact on the climate?
More oxygen causes more storms
More oxygen in the atmosphere increases plant growth
Ozone is part of what protects us from harmful UV radiation.
More oxygen leads to increased human overpopulation and desertification
The ozone hole is actually an area of depleted ozone in Earth’s atmosphere. Which of the following human activities has the greatest contribution to the development of the ozone hole?
The use of oil in automobile engines
The use of airplanes in the atmosphere
The increase in factory emissions
The use of chlorofluorocarbons in refrigeration
In the 1800s rabbits were introduced for the first time into Australia. Here they had no natural predators and a plentiful food supply. What happened several years after the rabbit was introduced into Australia?
The rabbits began to overpopulate greatly.
Populations of animals competing with rabbits grew.
The rabbit population declined sharply.
New rabbit predators evolved.
The design of air conditioners and aerosol cans has been changed in the last few years in an attempt to reverse which ecological problem?
deforestation
freshwater pollution
hole in the ozone layer
acid rain
Poisons such as DDT build up in lakes and streams due to runoff. Then they enter the food chain. Once in living organisms, the poisons are not broken down and their concentrations increase as they are passed along the food chain.
Which term best describes this ecological phenomenon?
global warming
loss of biodiversity
biological magnification
loss of genetic diversity
The burning of coal releases sulfur dioxide gas. How might the burning of coal lead to damaged plant life?
Sulfur dioxide can combine with drops of water to form acid rain.
Sulfur dioxide causes the remains of animals to decompose at a faster rate.
Sulfur dioxide gives off heat that raises the temperature of bodies of water.
Sulfur dioxide is a radioactive material that is dangerous for many years.
How are greenhouse gasses harming our environment?
They aren't
Less heat is able to escape causing the Earth to cool down
Less heat is able to escape causing the Earth to warm up
More heat is able to escape
What evidence is there to support that Global Warming is occurring?
Rising ocean temperatures
Declining arctic sea glacers
Sea levels rising
Increase in carbon dioxide in the atmosphere
Which organism shown in the food chain has the highest concentration of pollutants?
plankton
small fish
large fish
shore bird
Today the human population of Earth is
more than 10 billion
more than 6.7 billion
less than 7 million
less than 9.9 million
Drawbacks of solar energy are:
it is not always available
it is polluting
it is still quite expensive
all ot the other options
What is a disadvantage of wind turbines?
They pollute the air.
They do not pollute
They produce noise and may harm some animals
They are "green" energy
Geothermal resource extraction and its power plant operation emits zero CO2.
True
False
Biomass can converted into fuel such as biodiesel and bioethanol
True
False
What do you call the process of drilling and injecting fluid into a ground at a high pressure in order to break or fracture the shale rocks to release natural gas inside?
Drilling
Fracking
Perforation
Sedimentation
a species that is not native to a particular region and has no natural predators and little competition
consumer species
producer species
invasive species
adapted species
Forest clearing, farming, and road building are all examples of

Population distribution
Habitat loss
Climate Change
The greatest cause of biodiversity loss today is
Pollution
Habitat loss and change
Climate Change
Invasive species
The ability of an organism to remain unaffected by a harmful agent in the environment
chronic toxicity
acute toxicity
resistance
monoculture
How can we help to reduce plastic pollution?
We should use paper/cloth bags.
We should use less plastic.
We should refill our drinking bottles not buy new ones.
We should avoid (unikać) plastic or styrofoam containers.
All answers are correct.
There are plastic trash islands floating (dryfujące) on oceans.
