- Q2Which statement best represents the relationship between a producer and a consumer?A snake catches a frog and swallows it whole.A panda eats bamboo.A dog chews on a bone.A polar bear kills and eats a seal.300s
- Q3Into which trophic level will herbivores most likely be placed?third levelfirst levelfourth levelsecond level300s
- Q4Which would most likely happen if the Bluegill population decreased significantly?The Zooplankton population would start being consumed by the Kingfisher population.The Minnows population would decrease in number.The Crayfish population would compete with the Minnows for food.The Kingfisher population would decrease in number.300s
- Q5Which is the correct representation of energy flow through an ecosystem?sun - autotrophs - heterotrophswater - squirrels - nutssun - consumers - producersautotrophs - heterotrophs - sun300s
- Q6Which correctly displays the direction energy flows in a food chain?aphid - rose plant - beetle - hawk - mousebeetle - rose plant - mouse - hawk - aphidrose plant - aphid - beetle - mouse - hawkhawk - mouse - beetle - aphid - rose plant300s
- Q7Which organisms are found at level Y?primary consumerstertiary consumersproducerssecondary consumers300s
- Q8In which level is most of the available energy located within an energy pyramid?The third-order consumer has the largest amount of available energy because it is at the top of the energy pyramid.The producer level has the largest amount of available energy because it stores energy from the sun and supports all other trophic levels.The first-order consumer has the largest amount of available energy because it requires less energy to digest its vegetarian diet.The second-order consumer has the largest amount of available energy because more energy is obtained from a meat-eating diet than from plants.300s
- Q9As energy flows through each trophic level of the food chain approximately what percentage of energy is available to the next trophic level?100%10%1%50%300s
- Q10Which best describes energy transfer in an ecosystem among trophic levels?Approximately ninety percent of all energy is used at each trophic level.No energy is used in an ecosystem.Approximately half of all energy is used at each trophic level.Approximately ten percent of all energy is used at each trophic level.300s
- Q11The branch of biology dealing with interactions among organisms and between organisms and their environment is calledgenetics.ecology.zoology.botany.300s
- Q12The algae at the beginning of the food chain aredecomposers.consumers.heterotrophs.producers.300s
- Q13An organism that cannot make its own food is called aproducer.autotroph.chemotroph.heterotroph.300s
- Q14A community in which barn owls and snakes consume only mice is observed. If the number of snakes increases which of the following is most likely to happen first?the barn owl population will increasethe mouse population will decreasethe mouse population will remain the samethe barn owl population will decrease300s
- Q15Which represents the most likely flow of energy through an ecosystem?grass → mouse → snake → hawkmouse → grass → hawk → snakesnake → mouse → grass → hawkhawk → snake → mouse → grass300s
