1 What class is this? A.) biology B.) biology C.) biology D.) biology

2 Which of the following is NOT one of the factors that play a role in population growth rate? A.) immigration B.) death rate C.) emigration D.) demography

3 All the living and non-living things in an area make up an: A.) abiotic factor B.) ecosystem C.) population D.) tundra

4 Alligators in wetland regions normally feed on animals such as shorebirds. Shorebirds usually feed on small fish and frogs to survive. Recently, scientists released a large number of alligators into a wetland region. Scientists expect that as a result of this increase in the alligator population, the populations of small fish and frogs will A.) remain about the same B.) rapidly decrease C.) become extinct. D.) notably increase

5 The relationship one organism has with another organism is known as: A.) biosphere B.) symbiosis C.) population D.) predation

6 The hunting and killing of one organism by another organism is known as: A.) commensalism B.) predation C.) parasitism D.) mutualism

7 When organisms want to use the same resources it can result in: A.) climax community B.) succession C.) parasitism D.) competition

8 Which of the following series correctly represents the levels of organization within ecology from smallest to largest? A.) ecosystem -> population -> community -> biosphere B.) biosphere -> community -> population -> ecosystem C.) community -> population -> ecosystem -> biosphere D.) population -> community -> ecosystem -> biosphere

9 When individuals in a population reproduce at a constant rate, it is called A.) logistic growth B.) growth density C.) multiple growth. D.) exponential growth

10 The movement of organisms into a given area from another area is called A.) immigration B.) population shift. C.) emigration D.) carrying capacity.

11 There are 150 Saguaro cactus plants per square kilometer in a certain area of Arizona desert. To which population characteristic does this information refer? A.) growth rate B.) geographic distribution C.) age structure D.) population density

12 In secondary succession which of the following is a true statement: A.) it happens before a natural disaster occurs B.) it happens on bare rock C.) it occurs after a natural disaster D.) pioneer species time period is longer

13 The relationship where an orchid plant attaches itself to a tree branch without doing any harm to the tree is known as: A.) parasitism B.) mutualism C.) commensalism D.) ecosystem

14 An organism that obtains energy by hunting then eating dead organisms is called a(an)______ A.) producer B.) chemotroph C.) autotroph D.) scavenger

15 The biome characterized by drought resistant plants with animals and plants that adapt to extreme hot and cold conditions is: A.) rainforest B.) taiga C.) tundra D.) desert

16 Growth with unlimited resources is called: A.) exponential growth B.) logistical growth C.) succession D.) energy

17 Plants use carbon dioxide to build organic molecules during the process of … A.) transpiration. B.) photosynthesis. C.) respiration. D.) combustion

18 What is the original source of almost all the energy in most ecosystems? A.) carbohydrates B.) sunlight C.) water D.) carbon

19 Which of the following descriptions about the organization of an ecosystem is correct? A.) Communities make up individuals, which make up populations. B.) Populations make up individuals, which make up communities C.) Individuals make up communities, which make up populations. D.) Individuals make up populations, which make up communities

20 A relationship between a producer and consumer is best illustrated by a_____________. A.) snake eating a bird B.) lion eating a zebra. C.) fox eating a mouse. D.) zebra eating grass

21 Which of the following is NOT likely to be a limiting factor on the sea otter population? A.) disease B.) predation C.) competition D.) drought

22 Which level of organization includes all of the other levels? A.) organism B.) ecosystem C.) population D.) community

23 Which of the following is NOT a characteristic of all living things? A.) growth and development B.) ability to move C.) response to the environment D.) ability to reproduce

24 Only 10 percent of the energy stored in an organism can be passed on to the next trophic level. Of the remaining energy, some is used for the organism’s life processes, and the rest is A.) used in reproduction B.) stored as body tissue C.) stored as fat D.) eliminated as heat.

25 The total amount of living tissue within a given trophic level is called the. A.) organic mass B.) trophic mass C.) energy mass. D.) biomass

26 All of the members of a particular species that live in one area are called a(an) A.) biome B.) population. C.) community. D.) ecosystem

27 The sulfur and nitrogen compounds in smog combine with water to form A.) ozone B.) acid rain C.) ammonia. D.) chlorofluorocarbons

28 Why are fossil fuels nonrenewable? A.) They require hundreds of millions of years to form B.) Their ecosystems change forever when they are burned. C.) They are converted to carbon dioxide when they are burned. D.) They exist in a very small supply.

29 The movements of energy and nutrients through living systems are different because A.) energy flows in one direction and nutrients recycle B.) energy is limited in the biosphere and nutrients are always available C.) nutrients flow in one direction and energy recycles. D.) energy forms chemical compounds and nutrients are lost as heat.

30 Carbon cycles through the biosphere in all of the following processes EXCEPT A.) photosynthesis B.) transpiration C.) burning of fossil fuels. D.) decomposition of plants and animals

31 Which of the following is NOT recycled in the biosphere? A.) water B.) nitrogen C.) carbon D.) energy

32 What would be the most likely effect of an increase in the use of CFCs? A.) The ozone layer would suddenly disappear B.) The ozone holes would get smaller C.) The ozone holes would get larger. D.) There would be no effect on ozone in the atmosphere

33 The number of different species in the biosphere is called A.) biodiversity B.) ecosystem diversity C.) genetic diversity D.) species diversity

34 Which animal would be found in the biome that has cold to moderate winters, warm summers, fertile soils, and is home to a variety of vegetation, such as coniferous trees, broadleaf deciduous trees, flowering shrubs, and ferns? A.) whitetail deer B.) polar bear C.) iguana D.) moose

35 What is one difference between primary and secondary succession? A.) Primary succession is slow and secondary succession is rapid B.) Secondary succession begins on soil and primary succession begins on newly exposed surfaces C.) Primary succession modifies the environment and secondary succession does not. D.) Secondary succession begins with lichens and primary succession begins with trees

36 Several species of warblers can live in the same spruce tree ONLY because they A.) have different habitats within the tree B.) eat different foods within the tree. C.) occupy different niches within the tree. D.) can find different temperatures within the tree.
