In nature, which type of behavior causes animals to produce aggressive displays and sounds?
imprinting
territoriality
conditioning
habituation
What will most likely occur if the population of the world continues to increase at predicted rates?
There will be an increase in biodiversity as a result of improvements in technology.
There will be more rapid depletion of natural resources.
The human race will rapidly become extinct.
All human diseases will be eliminated
What will most likely happen if a nonnative species is introduced into a stable ecosystem?
The native species will change their diet, and the ecosystem will remain stable.
The native species will move to another area, and the ecosystem will remain stable.
The native species will have to compete for resources with the nonnative species, and the ecosystem will become unbalanced.
The native species will share their food with the introduced species, and the ecosystem will become unbalanced.
Which statement best explains why animals are considered heterotrophic?
They are able to produce food through the process of photosynthesis.
They are able to produce food through the process of respiration.
They are able to obtain nutrients by decomposing plant and animal tissue.
They are able to obtain nutrients by consuming other organisms or their products.
In some ecosystems, wolves have been eliminated due to their threats to humans. How can the reintroduction of wolves benefit the ecosystem?
It can eliminate weak animals from a prey population, thereby decreasing competition for natural resources.
It can eliminate the most fit animals among the prey population, which will cause an increase in birthrates of the prey.
It can cause the prey population to migrate to other areas, resulting in more fit prey.
It can cause the prey population to better blend in with their environment.
What will most likely be the result as humans move into new areas, forests are clear cut and housing developments are built?
Global temperatures will decrease because trees are removed.
Many organisms will lose their homes because their habitats have been destroyed.
Better sanitation in the area will reduce the amount of pollution.
The rainfall in the area will increase because there will be increased runoff.
What activity most contributes to the depletion of the ozone layer?
burning fossil fuels
release of CFCs
deforestation
overuse of fertilizers
The graph above represents the growth of a population in an area of....
infinite resources
limited resources
no competition
courtship.
Why are many farmers encouraged to plant different types of crops on the same land throughout the year?
It prevents insects from destroying crops.
It provides more food to other countries.
It allows for more genetic variation in plants.
It helps to preserve the quality of the soil
Two different populations of birds live in the same area and eat the same types of food. Which most likely describes the relationship between these two populations of birds?
competition
mutualism
parasitism
predator-prey
What will most likely happen if the human population continues to grow at current rates?
There will be fewer natural resources available for future generations.
There will be an increase in nitrogen levels in the atmosphere.
There will be a decrease in water pollution.
There will be an increase in the number of strong hurricanes.
A sea turtle has washed up on a remote section of a beach. This is known as a “stranding.” Stranding occurs when a dead, sick or injured sea turtle washes up on the shoreline. Which statement best explains why “stranding” should be reported immediately to local authorities?
The information can be very useful to biologists and managers who are trying to protect the species.
The information can be very useful to protect sea turtles from predators.
The information can be very useful to local fishermen who try to catch fish that sea turtles eat.
The information can be very useful to tourists who may want to keep sea turtles as pets.
The males of a bird species do a “dance” and “sing a song” each spring. What is the main purpose of these behaviors?
to scare off young birds
to imprint young birds
to clean their feathers
to attract female birds
The yucca plant releases a strong scent at night when the yucca moth is active.
The yucca moth, attracted by the scent, gathers pollen from the yucca flower. The yucca moth then deposits her eggs and the pollen on another plant. This ensures that the plant will be cross-pollinated and that the yucca moth larvae have a steady food supply.
Which relationship does this best illustrate?
commensalism
mutualism
parasitism
predation
Which environmental concern is most associated with burning fossil fuels?
global climate change
pollution of ocean waters
ozone layer destruction
decrease in levels of atmospheric carbon dioxide
The construction of a new coal-burning power plant would have the greatest impact on which environmental issue?
depletion of the ozone
production of acid rain
release of radiation
increase in deforestation
At night, moths travel toward light. Which type of behavior does this describe?
habituation
imprinting
innate behavior
learned behavior
Which environmental factor would cause the greatest decrease in the number of species of plants and animals living in some of the lakes in the United States?
increase in dissolved oxygen levels
global warming
ozone destruction
acid rain
If worldwide deforestation is not regulated, what could most likely result?
Acid rain could lower the pH of rivers and lakes to dangerous levels for aquatic life.
CO2 levels in the atmosphere could increase and contribute to global warming problems.
Plants and animals could become better adapted to living in desert conditions.
Future generations of humans could have an excess of wood and paper products.
