Which is a disadvantage of wind farms?
a wind farm produces more noise pollution than a single wind turbine produces
a wind farm produces less electricity than a single wind turbine produces
Which of the following is an advantage of building wind farms instead of a single wind turbine?
a wind farm can be built close to towns that need electricity
a wind farm can easily be built in locations away from birds
a wind farm produces enough sound to keep birds away
a wind farm produces a greater amount of electricity than a single wind turbine produces
Which type of human impact is shown in the picture below?
Desertification
Deforestation
Urban sprawl
Land pollution
Which of the following is an example of a non-renewable resource?
Solar Energy
Wind Energy
Hydro Energy
Fossil Fuel Energy
Which human activity has the potential to greatly affect the equilibrium of an ecosystem?
cutting down a few small evergreen trees and using them to make holiday decorations
mowing the playing fields in a city park
washing a car with a detergent-based cleaner
emptying an aquarium containing many nonnative fish of several species into a local lake
Sustainable development occurs when people use their resources without depleting them. Which human activity is the best example of sustainable development?
draining a wetland to build houses
loggers planting a tree for each one cut down
using nets to quickly capture large numbers of fish
building coal-burning power plants to provide electricity
The graph below shows how the introduction of the opossum shrimp, as a food source for salmon, affected a lake ecosystem in Montana. Based on the data in this graph, one likely conclusion that can be made is that over approximately ten years
the lake ecosystem stabilized after the introduction of the new species
competition between organisms was reduced as more producers were introduced into the lake
more predators moved into the lake ecosystem once the opossum shrimp were added
the introduction of the opossum shrimp into the lake ecosystem disrupted the food webs that were present
Orcas are endangered whales. Only about 80 individuals remain off the coast of Washington State. Salmon are a source of food for orcas. Some individuals are proposing that four dams in Washington State be removed so that habitat areas for salmon will be increased. Those opposed to the dam removals say that the dams provide low-cost hydroelectric power and positively influence the local economy. This situation is an example of
direct harvesting of an endangered orca species by humans
orcas overproducing in an ecosystem with no resources
a community relying on nonrenewable energy sources
a decision where benefits and risks have to be weighed
Building large manufacturing facilities can affect ecosystems by increasing the
atmospheric quality
biodiversity in the area
demand for resources such as fossil fuels
availability of space and resources for organisms
The governments of many countries have regulations that are designed to prevent the accidental introduction of nonnative insects into their countries. This is because, in these new habitats, the nonnative insects might
become food for birds
not survive a cold winter
not have natural predators
add to the biodiversity
Which human activity can have a negative impact on the stability of a mature ecosystem?
replanting trees in areas where forests have been cut down for lumber
building dams to control the flow of water in rivers, in order to produce electricity
preserving natural wetlands, such as swamps, to reduce flooding after heavy rainfalls
passing laws that limit the dumping of pollutants in forests
New York State charges consumers a fee when purchasing beverages sold in aluminum cans and plastic bottles. This money is returned to purchasers when they return these items for recycling. Programs such as these are an attempt to
encourage people to spend more money on their beverages
conserve the resources these containers are made from
reduce the amount of carbon dioxide produced by deforestation
totally eliminate the use of reusable containers
Global warming is most closely associated with
increased use of solar panels
increased industrialization
reducing the rate of species extinction
removal of environmental wastes
What impact do the amounts of available energy, water, and oxygen have on an ecosystem?
They act as limiting factors
They are used as nutrients
They recycle the residue of dead organisms
They control environmental temperature
Nutritional relationships between organisms are shown in the diagram below. The mouse population would most likely decrease if there were
an increase in the frog and tree populations
a decrease in the snake and hawk populations
an increase in the number of decomposers in the area
a decrease in the amount of available sunlight
In the diagram below, what does X most likely represent?
autotrophs
herbivores
decomposers
carnivores

A
B
C
D
The growth of a population is shown in the graph below. Which letter indicates the carrying capacity of the environment for this population?
A
B
C
D
A decrease in the biodiversity of an ecosystem usually leads to
an increase in predator and prey populations
the elimination of material cycling
a decrease in stability
an increase in dynamic equilibrium
A hummingbird may need to consume up to 50% of its body weight in sugar each day, just to meet its energy needs. Some of this energy is stored and some is used for metabolic activities, but much of the energy is
converted into amino acids needed for the production of starch
released as heat energy back into the hummingbird’s environment
changed into radiant energy, which can be used by plants for photosynthesis
used to synthesize inorganic compounds necessary for cellular respiration
Ringworm is a skin infection common among school-aged children. Although the name suggests that a worm causes the disease, it is actually caused by a fungus that lives and feeds on the dead outer layer of the skin. The relationship between ringworm and humans can be described as
predator/prey
predator/host
parasite/prey
parasite/host
Which list contains only abiotic conditions that might be found in a pond ecosystem?
temperature of the water, green plant populations, dissolved minerals in the water
temperature of the water, dissolved oxygen in the water, dissolved minerals in the water
bacteria, dissolved minerals in the water, temperature of the water
dissolved oxygen in the water, fish populations, insect populations
Which statement correctly identifies a possible role of one organism in this ecosystem?
Species A may carry out autotrophic nutrition.
Species B may be a producer that synthesizes nutrients.
Species C carries out heterotrophic nutrition.
Species D can recycle energy from the Sun.
