An example of recycling is
using a paper cup instead of a mug
turning off the lights when leaving a room
using plastic from a soda bottle to make a certain type of clothing
using two paper towels rather than five to clean up a spill
One characteristic of a stable ecosystem is
a high number of predators
an interdependence of organisms
a lack of biodiversity
an increase in human interference
According to scientists, ocean waves could be a source of energy. Devices are being designed to capture the energy from waves and supply electricity to coastal areas. A direct benefit of utilizing this technology to produce energy would be the
destruction of habitats near the devices
decreased use of nonrenewable resources
release of gases needed for photosynthesis
increased use of finite resources
The emerald ash borer is an insect that is thought to have been accidentally brought to the United States from China in shipping containers. It attacks ash trees, eventually killing the trees, destroying an important part of the ecosystem. The presence of the emerald ash borer in the United States can be used as an example of how humans have
purposely introduced an insect to correct a problem in an ecosystem
used an insect to remove one insect species and replace it with another
worked to increase the biodiversity in a particular area
altered the equilibrium in an ecosystem by introducing a new species
The burning of fossil fuels has harmed the environment by
decreasing acid rain in the northeast United States
adding carbon dioxide to the atmosphere
increasing biodiversity in the lakes and ponds of the Adirondack
depleting the ozone shield directly over western New York State
Which method of collecting data would provide the most accurate information about how an ecosystem is being affected by human development?
The people in the neighborhood record the number of birds they see in the area both before and after the construction of a new building.
Deer in the area are identified before construction so that scientists can see where they go after the building is finished.
More trees are planted in the area around the construction site to allow the animals a new place to live.
The population size is recorded for each species present in the construction area before and after the building is completed.
Many biotic factors affect individuals in a population. An example of an organism being directly affected by a biotic factor is
a squirrel cannot find a mate
a flood washes away a maple tree
a plant is in a dark room
a chipmunk finds a rock pile to use for a home
Which statement best describes what is most likely to occur if an animal population grows larger than the carrying capacity of its environment?
The birth rate will increase.
Both the birth rate and death rate will decrease.
The death rate will increase.
Neither the birth rate nor the death rate will decrease
A chemical was added to hand sanitizers and dish detergents to kill bacteria. Certain species of bacteria are no longer killed by this chemical. One likely reason for the decreased effectiveness of this chemical is that these bacteria have
slower metabolic rates
a mutation for resistance
been selectively bred for survival
green plants make energy-rich compounds available
Which level of the pyramid below is correctly paired with the type of organism that would most likely be found at that level in an ecosystem?
Level A - Producers
Level B - Carnivores
Level C - Herbivores
Level D - Decomposers

1
2
3
4
As a result of habitat destruction, the size of the Florida panther population has been drastically reduced. It is estimated that there are only 100 to 160 Florida panthers in the wild. Which statement best explains why the Florida panther population may not continue to evolve?
There is no longer a chance of mutations occurring in the population.
There is a lack of competition for limited environmental resources.
There is no longer a chance of a trait providing a reproductive advantage to the population.
There is a lack of genetic variation for selection to act upon.
