Trivia On Biology EOC Practice Test! Quiz

Do you know trivia on biology, and do you think you can pass this quiz? During this quiz, you will need to understand what a first-level producer is, a second-level producer. Why are the activities of energy and nutrients all through living systems different? What does biotic factor mean, a symbiotic relationship, and the difference between primary and secondary succession? This quiz will help you understand biology. You will rock this quiz.

      consumer

    • B. 

      decomposer

    • C. 

      Producers

    • D. 

      consumers (your response) heterotrophs

      First level producer

    • B. 

      First level consumer

    • C. 

      Secong level producer

    • D.

  • 3. 
    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

  • 4. 
    Which is a biotic factor that affects the size of a population in a specific ecosystem?
    • A. 

      Average temperature of the ecosystem

    • B. 

      Type of soil in the ecosystem

    • C. 

      Number and kinds of predators in the ecosystem

    • D. 

      Concentration of oxygen in the ecosystem

  • 5. 
    The symbiotic relationship between a flower and the insect that feeds on its nectar is an example of
    • A. 

      Mutualism because the flower provides the insect with food, and the insect pollinates the flower

    • B. 

      Parasitism because the insect lives off the nectar from the flower

    • C. 

      Commensalism because the insect doesn’t harm the flower, and the flower doesn’t benefit from the relationship

    • D. 

      Predation because the insect feeds on the flower

  • 6. 
    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

  • 7. 
    A forest fire destroys the majority of the trees in a state park. Which effect will this most likely have a secondary consumers in that ecosystem?
    • A. 

      The amount of available energy will increase because there will be fewer predators in the forest

    • B. 

      The amount of available energy will increase because there will be less competition from producers.

    • C. 

      The amount to available energy will decrease because fewer primary consumers will survive the lack of vegetation

    • D. 

      The amount of energy will remain constant because secondary consumers are not reliant on primary consumers

  • 8. 
    A new species of snake was introduced to a tropical region. Scientists noticed a steady decline in the presence of field mice and an increase in the number of snakes. Which of these is the MOST LIKELY explanation about why the population size of each animal changed?
    • A. 

      The snakes introduced to the region dominated the habitat, forcing the mice to find another place to live

    • B. 

      The mice became prey to the intoduced snakes, allowing the snake population to increase but decreasing the mice population.

    • C. 

      The snakes introduced to the region competed with the mice for food, allowing the snake population to increase but decreasing the mice population.

    • D. 

      The people in the surrounding area set traps that killed the mice, allowing the snakes to live without any predators and therefore to increase the number.

  • 9. 
    If a population grows larger than the carrying capacity of the environment, the
    • A. 

      Death rate may rise

    • B. 

      Birth rate may rise

    • C. 

      Population will grow faster

    • D. 

      Carrying capacity will change

  • 10. 
    All of the following are threats to biodiversity EXCEPT
    • A. 

      Biological magnification of toxic compounds

    • B. 

      Habitat fragmentation

    • C. 

      Invasive species

    • D. 

      Species preservation

  • 11. 
    One species of Galapagos finches, the cactus finch, eats insects off cactus plants. A disease kills off most of the cacti in the Galapagos Islands. Which of these most likely would happen to the carrying capacity of the island?
    • A. 

      It would increase a small amount since the insect population would decrease

    • B. 

      It would remain about the same since the finches would change to a different habitat

    • C. 

      It would increase exponentially since the insects would have limited places to hide

    • D. 

      It would decrease considerably since the finches are specifically adapted to their niche

  • 12. 
    Polar bears swim across large expanses of the ocean while hunting for seals, their main source of food. The bears use sea ice as a resting spot during their long swims. However, sea ice is rapidly melting as a result of global warming. Which statement describes what most likely will happen if global warming continues at its present rate?
    • A. 

      Polar bear and seal populations will both increase

    • B. 

      Polar bear populations will decrease, and seal populations will increase

    • C. 

      Polar bear populations will increase, and seal populations will decrease

    • D. 

      Polar bear populations will decrease, and seal populations will remain the same

  • 13. 
    A population of salamanders that live in a river requires clear, freshwater to survive. A flood causes tons of sediment to be suspended in the river. Which of these most likely will happen to the salamander population?
    • A. 

      The salamanders will adapt to life on land

    • B. 

      The salamanders will move to another river.

    • C. 

      The salamanders will adapt to living in the muddy water

    • D. 

      The salamanders will decrease in number because of the water quality

  • 14. 
    No two species can occupy the same niche in the same habitat at the same time
    • A. 

      Because of density-independent factors

    • B. 

      Unless the species require different abiotic factors

    • C. 

      Because of the competitive exclusion principle

    • D. 

      Unless the species require different biotic factors
