100
128
256
320
Which determines carrying capacity?
logistic factors
exponential growth
population growth
limiting factors
Which would have to happen to keep the population growth of cheetahs the same in 2013?
4 deaths, 7 births, 2 immigration, 6 emigration
3 deaths, 6 births, 5 immigration, 7 emigration
5 deaths, 2 births, 8 immigration, 3 emigration
1 deaths, 5 births, 3 immigration, 7 emigration
Which of the following is a limiting factor for a ground squirrel population?
a population of tree squirrels
a population of hawks
genetic variability
breeding season
The Serengeti plains are part of the African savanna ecosystem and are home to a variety of different species of plants and animals. The Serengeti plains experience a seven-month period of seasonal drought each year, during which the ecosystem receives only four inches of rain and the availability of some resources becomes very scarce. Which type of limiting factors does the seasonal drought in the Serengeti plains affect?
density-independent factors
density-dependent factors
population-dependent factors
population-independent factors
An ecosystem has experienced a flood. Which type of plants would you expect to see growing first after the flood?
Shrubs
lichen
small annual plants
pine and oak trees
Which would be the most accurate title for this picture?
primary succession after a controlled fire
primary succession after a volcanic eruption
secondary succession after a controlled fire
secondary succession after a volcanic eruption
What would happen to the size of the mountain lion population if the deer population increased?
decrease
increase
die off
stay the same
What is the difference between food chains and food webs?
Food webs show the flow of energy from producers to consumers, and food chains show the flow of energy from consumers to producers.
Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.
About ten percent of the energy is passed on to the next trophic level in food webs, but in food chains, about ninety percent is passed on to the next trophic level.
Heat is lost when energy is passed onto the next trophic level in food chains, but in food webs, heat is not lost when energy is passed on to the next trophic level.
A grass starts with 30,000 kJ of energy. How much energy would a cheetah acquire after it ate a zebra that consumed the grass?
30 kJ
300 kJ
3,000 kJ
30,000 kJ
If the Mountain Lion is removed from the food web, what will most likely happen?
Nothing will change in the food web
The robin population will increase
The deer population will increase
The fox population will decrease
White perch is a fish that is native to Atlantic coastal regions and is invasive to the Great Lakes. It feeds on native species and is thought to be the cause of the decline of the Great Lakes walleye fish populations. What was most likely its mode of introduction?
produce brought from the eastern states
trapped in a ship's ballast or a water tank
trapped in a cargo crate carrying nonperishable items
luggage brought in an overseas flight
What is the difference between a community and a population?
A community has only one organism, while a population has many organisms.
A population has only one ecosystem, while a community has many ecosystems.
A community has only one biome, while a population has many biomes.
A population has only one species, while a community has many species.
What best describes the association between the carbon cycle, plants, and animals?
Plants fix carbon and release oxygen, and animals release carbon and use oxygen.
Animals fix carbon and release oxygen, and plants release carbon and use oxygen.
Animals fix carbon through respiration, and plants fix carbon through photosynthesis.
Plants decompose fixing carbon, and animals decompose releasing carbon.
Which explanation is best supported by the numbers in the chart?
Lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetahs.
The dwindling zebra population has led to the decline of the predator lion and cheetah populations.
Overhunting of lion and cheetah populations has led to a decline in the food source population.
Lion and cheetah populations compete for the food source of zebras, and cheetahs outcompete lions.
Scientists use specific levels of organization to analyze the biosphere. The Everglades consist of a large area of subtropical wetlands in Florida. Various species of plants and animals can be found in the Everglades, including panthers, cypress trees, herons, and alligators. The group of ecosystems on Earth that feature climate, vegetation, and wildlife similar to the Everglades is
a biosphere.
a community.
a population.
a biome.
Hyenas and lions have fierce battles over food. Which type of relationship does this describe?
Parasitism
Commensalism
Predation
Competition
Legumes, a type of plant, require Rhizobia, a type of soil bacteria, to survive since these organisms fix nitrogen. Rhizobia use legumes for food. What would most likely happen to the legume population if Rhizobia suddenly became extinct?
become extinct
learn to fix nitrogen
benefit in the long run
stay the same
A relationship in which one organism benefits while the other is neither harmed nor helped is called
Predation.
Parasitism.
Commensalism
Mutualism
Arianne recently traveled abroad where she enjoyed eating food from different countries and learning about different cultures. A week after she returned home, she checked into the hospital with signs of nausea, fever, and diarrhea. What best explains what happened to Arianne?
A parasitic bacteria contaminated her food.
A mutualistic bacteria infected her digestive system.
A commensalistic organism is now living in her intestine.
A predatory organism is consuming her natural bacteria.
What is global warming?
the normal temperature fluctuations of Earth's climate cycle
the melting of the polar ice caps
the trend of increasing temperatures on Earth

What is one of the greatest threats to biodiversity on Earth?
habitat destruction
loss of drinking water
decrease in food supply
Pollution
The process in which populations change over time
Ecology
Natural Selection
Evolution
Mutation
Nature has a way of causing organisms that inherit advantageous traits to survive and reproduce more successfully than the ones that don't. This process is known as…
Genetic variation
Adaptation
Overproduction
Natural selection
