Total questions: 25
Worksheet time: 15mins
Introduced species only become pests because they….
increase biodiversity, because they attract new species to places where they settle.
have a low genetic variability, enabling them to live in a wide variety of habitats
can live in many niches, easily adapt to many variables, and eat a wide variety of food
inhabit only niches that have recently become available after the local extinction of another species.
The biggest threat to biodiversity is
asteroid strikes, such as what happened 65 million years ago, resulting in the extinction of the dinosaurs
habitat destruction, such as cutting down portions of tropical rain forests, which destroys the niches occupied by organisms in that habitat
human population growth, because as population increases, so does the number of plants and animals they eat, resulting in a decrease in those organisms
an increase in climate change, because it will result in many species moving northward or to higher elevations as they seek out their necessary habitat
Which of the following would prevent invasive species from being introduced and becoming established?
Inspect foreign goods before they enter the country
Allow ships to discharge their ballast water when they enter port
Establish international treaties banning the transfer of species across borders
Which of the following international treaties bans the hunting, capturing, and selling of threatened or endangered species in 178 countries?
Convention on International Trade in Endangered Species (CITES)
The National Marine Fisheries Act
International Environmental Policy Act (IEPA)
Endangered Species Act (ESA)
Which is not a trait of an invasive nonnative species?
No natural predators
Generalist
High reproductive rate (r strategist)
Unsuccessful at establishing itself in the environment
One reason for the decline in recent years of global fish catch is
approximately 4 million fishing boats use modern technology to hunt vast numbers of fishes in open ocean.
invasive species, especially those introduced in ballast water, prey upon and destroy the habitat of native fishes.
bottom trawling scrapes the ocean floor, destroying habitats where many fishes live.
What is fishprint?
The impact a fish species has on its environment
The impact the fishing industry has on the environment
Area of ocean needed to sustain the consumption of an average person, nation, or world
Which of the below has a cooling effect on the earth's atmosphere?
Aerosols such as sulfate particles
Condensation trails left by jet planes
Particulate matter from burning grasslands and forests
Water condensation on planes
Which of the following is an unavoidable effect of the current warming trend of the earth?
Flooding of the low-lying cities and island nations
Bleaching of the coral reefs and spread of deserts
Melting of the permafrost and tundra, releasing methane gas
Collapse of the Amazon rain forest
Which of the below is a positive feedback mechanism that could be accelerating the warming of the earth's atmosphere?
Severe drought, causing the earth to be browner and absorb more radiation
Spraying of sulfate particles in the atmosphere, reflecting light
Absorption of CO2 by the oceans
Changing of ocean currents, carrying heat to different places
The ozone layer blocks (choose all that apply)
UV-B
UV-C
UV-A
The specific atom in HCFCs that causes ozone trouble is
Chlorine
Hydrogen

Carbon
Chlorine causes the buildup of what in the stratosphere?
Oxygen
CFCs
Ozone

Which continent does most ozone depletion occur?
(a)
What was the agreement among nations to stop producing CFCs?
The Kyoto Accord
The Montreal Protocol
The Green New Deal
When solar radiation hits the earth or the atmosphere, it is absorbed and then released as
(a)
What happens to most incoming solar radiation?
Reaches earth's surface and is absorbed or reflected
Absorbed by atmosphere and clouds; reradiated as heat
Reflected into space
Right now, what is having the largest effect on sea level?
Water added by ice melting
Thermal expansion of water
Not enough information to tell
Barrier islands provide what benefits that could be lost as sea levels rise as a result of climate change? Choose all that apply.
Erosion control
Reduced damage to property from tropical storms
Decreased sediment pollution.
Habitat for organisms with a wide range of tolerance
Heat absorbed by the ocean (select all answers that correctly finish the sentence)
is moved around the globe by ocean's current.
remain in the ocean for decades.
does not have an effect on global climate.
Remains near the ocean surface.
Ocean organisms mating patterns can be disrupted by climate change because many mating seasons are triggered by a change in
(a)
As atmospheric CO2 increases, the amount of H+ ions dissolved in the ocean will
Increase
Decrease
Stay the same
Nonnative species are (choose all that apply)
usually generalists.
often without predators in new environment.
always deliberately introduced by humans
K-selected
the most effective strategy to protect an endangered species is to
protect the habitat of the species.
legislate policies to protect endangered species.
hire armed guards for the species.
