    special structures & behaviours that help an organism succeed in its ecosystem.

3. Biodegradable items were

    invented before the 80's.

    once living and can be broken down by decomposers.

    only consumed by species known as producers.

    only present in flora & not fauna.

4. Biomes are:

    are parts of a leaf.

    to be recycled by law.

    a collection of related ecosystems.

    None of the above.

5. Biotic components of an ecosystem include:

    decomposers, producers & consumers.

    the underground sections of the biosphere.

6. All of the organisms in an ecosystem refers to the

    the matter cycle.

    the carbon cycle.

    the community.

    party at ground zero.

7. To break down into smaller pieces to be reused in an ecosystem is to



    reduce biodiversity.

    buy a motorcycle.

8. The variety of living organisms in an ecosystem refers to

    a zoo.

    Farmer Brown.



9. Ecology

    is the opposite of biology.

    studies the relationship between an environment's components.

    studies only biotic components.

    is for the birds.

10. An Ecosystem refers to the relationships among

    organisms in a community & the abiotic factors in their environment.

    flora & fauna.

    Mowgli & Baloo.

    producers & consumers.

11. The term Ecological Niche refers to

    the role of technology.

    human intervention.

    a field study.

    the role of an organism in an ecosystem. (How it's uniquely successful.)

12. Scientists look at food chains to

    organize & understand how species interact & to show feeding pathways of several organisms.

    discover nutrients.

    buy discounted pizzas.

    understand how respiration breaks down sugars for the energy stored.

13. Substances that supply organisms with energy to move, grow & repair cells.

    Mom's cooking.




14. Everyone knows that an organism is

    the number of a certain species in a population.

    a single living thing.

    the variety of populations in a community.

    only referring to animals instead of a plants.

15. Farmers use pesticides to

    increase biodiversity within an ecosystem.

    to encourage nocturnal photosynthesis.

    to reduce the populations of unwanted plant and animal populations.

    None of the above.

16. Photosynthesis is a process in which plants

    transfers heat from the sun into energy for cell growth & repair.

    in the ocean consume algae.

    fend off scavenger species.

    cause the pH of groundwater to decrease rapidly & create acid rain.

17. A Producer is

    a plant that produces all the food & oxygen that consumers need.

    is the hardest working person on the movie set.

    at the top of most food chains.

    None of the above.

18. A Pioneer species is

    a scavenger in its ecosystem.

    an omnivore in its ecosystem.

    the first species that arrives (back) in an ecosystem (ie. After a severe forest fire).

    David Suzuki

19. Succession

    is achieved when studying for a test!

    is a predictable pattern of change in an ecosystem.

    is survival of the fittest.

    proves the theory of evolution.

20. The Hydrologic Cycle refers to

    Mr. F's next bike.

    various forms of precipitation.

    hydroelectric power generation (damming rivers for electricity).

    None of the above.

21. Population refers to

    the number of organisms of the same species in a community.

    the number of species in a community.

    the number of organisms of the same species in a biome.

    the number of organisms of the same species in the biosphere.

22. Omnivores are

    fauna that consume both flora & fauna.

    flora that consume both flora & fauna.

    lower on most food chains than producers.

    None of the above.

23. The Matter Cycle describes

    how matter is used & reused by organisms.

    the role of decomposers in an ecosystem.

    the importance of biodegradable items in forest biomes.

    how human-made chemicals break down molecules.

24. A Decomposer is

    a type of species that scavenges in an ecosystem.

    an ecological niche; an organism that breaks down materials to be reused in ecosystems.

    loves rap music.

    not overly fond of Mozart's Flute Concerto No. 2 in D Major.

25. The Carbon Cycle shows how

    to make lightweight bicycles.

    carbon in CO2 from the atmosphere is NOT used to make sugars for plants/animals.

    carbon is used / reused in respiration & photosynthesis.

    chlorophyll absorbs light in the electromagnetic spectrum.

26. The Biosphere is


    wherever living things are found in water biomes.

    wherever organisms are found on earth.

    at Farmer Brown's.

27. Biological amplification is the process that results in

    Biological amplification is the process that results in

    increasing concentrations of harmful chemicals at each higher level of a food chain.

    organisms reproduce & have offspring larger than themselves.

    decreasing concentrations of harmful chemicals at each higher level of a food chain.

28. Microbes

    assist in the recycling of matter & in turn provide nutrients to producers.

    are also known for disease causing bacteria & viruses.

    are useful in making cheese, yogurt, bread & tanning leather.

    All the above.

29. Which statement is true?

    Microbes are not responsible for epidemics.

    There are 7 kinds of microbes.

    Every organism in an ecosystem serves a function.

    Mr. Fitch's favourite colour is NOT chrome.

30. Four types of microbes are:

    Producers, Consumers, Decomposers & Scavengers.

    Viruses, Bacteria, Protozoans & Fungus.

    Viruses, Bacteria, Decomposers & Fungi.

    Disease, Epidemics, Influenza & pandemics.

31. Four examples of types of microbes are:

    HIV, gangrene, malaria & moulds.

    Nutrients, vitamins, sugars & carbohydrates.

    Smallpox, HIV, polio, influenza (the Flu).

    Honda, Yamaha, Kawasaki & Suzuki.

32. Which statement is NOT true?

    Mr. F. loves motorbikes.

    The extinction of species is a natural process.

    Acid rain has a high pH.

    Coal burning plants, metal smelters & oil refineries produce energy, materials & air pollutants.

33. Which items do NOT belong in municipal landfills?

    Recyclable paper & metals.

    Toxic elements such a mercury & highly radioactive metals.

    Used tires, disposable diapers, consumer electronics & non-biodegradable plastics.

    All of the above.
