Several factors can lead to soil erosion. Which of these human activities is most likely to contribute to soil erosion?Planting trees and vegetationClearing land for farmingDesignating land as a wildlife habitatReducing the amount of livestock in an area2. One job that many governments have is stewardship of Earth's resources. Stewardship is the careful and responsible management of a resource. Why is stewardship of Earth's resources important?It prevents people from using resources.It keeps governments stable.It gives people the opportunity to vote.It ensures that resources will not be polluted or used up too quickly.3. A fungus is an example of:An herbivoreA saprophyteAn autotrophAn omnivore4. An example of a producer is:CaterpillarFungusBirdWater Lily5. We can reduce land pollution by _________________________________________.I: incinerating rubbishII: reducing deforestationIII: using organic pesticides in farmingIV: building taller chimneys for factoriesII and III onlyI, III and IV onlyI onlyI and III only6. Which of the following are non-biodegradable materials?I: WoodII: PlasticsIII:Styrofoam boxIV: Prawn shellII and III onlyII, III, and IV onlyI and II onlyI, II, III, and IV7. The burning of fossil fuels can lead to acid precipitation. What do fossil fuels generate that is needed to form acid precipitation?Particulate pollutantsWaterGas pollutantsEnergy8. Earth's surface is mostly water. However, only a small amount of water on Earth is clean freshwater. Why is it important to maintain water quality?To keep the polar ice caps from meltingTo keep the ocean levels from loweringTo keep water from becoming a nonrenewable resourceTo keep water from evaporating9. Which of these food chains is in the correct order?Water lily, frog, caterpillar, snakeCaterpillar, water lily, frog, snakeSnake, frog, caterpillar, water lilyWater lily, caterpillar, frog, snake10. Which of the following would be considered a natural resource?PlasticRockSteelConcrete11. Lynnette is categorizing natural resources. Which of these is a nonrenewable resource she should include on her list?WindOilWaterSolar energy12. Untreated sewage promotes the growth of algae and encourage the growth of marine plants.TrueFalse13. One biotic factors that limits the carrying capacity of any habitat isAmount of soil erosionThe availability of waterLevel of atmospheric oxygenActivity of decomposers14. What are the three factors a niche includes?Food, competition, energy pyramidHabitat, ecology, foodFood, Nonliving conditions, behaviorHabitat, food chain, oxygen cycle15. Which is an abiotic factor that would affect the ability of a species of tree to survive in a particular habitat?Availability of minerals in the soilType and number of tree parasitesClimax vegetation of the areaType and number of herbivores present16. Scientists use absolute dating to determineThe chemical composition of rocksThe numerical age of an object in yearsThe approximate date of a rock layer or fossilThe physical appearance of fossils17. The removal of nearly all the predators from an ecosystem would most likely result inA decrease in the size of decomposersA decrease in new predators migrating into the ecosystemAn increase in the number of herbivoresAn increase in the number of carnivore species18. Millions of automobiles are on roads around the world every day. The image below shows one effect of car travel. What does the image best illustrate?Acid precipitationGlobal warmingAir pollutionUrbanization19. Which rocks can be changed into sediments by weathering and erosion?IgneousSedimentaryAll of theseMetamorphic20. Coal is a nonrenewable natural resource. Why is coal considered nonrenewable?Coal will never run out.No new coal is being produced on Earth.Coal is used to produce energy and not materials.Coal is being used faster than it is being produced.21. Which human activity will most likely have a negative impact on global stability?Decreasing water pollution levelsIncreasing world population growthDecreasing habitat destructionIncreasing recycling programs22. Bart believes that mice exposed to radio waves will become stronger. To experiment he places 10 mice near a radio for 5 hours. Bart also tested a control group of 10 mice that were not exposed to radio waves. His test consisted of a heavy block of wood that blocked the mice food. He found that 8 out of 10 of the radio waved mice were able to push the block away and only 2 out of 10 of the non-exposed mice were able to do the same. What is the independent variable in Bart's experiment?The amount of mice exposure to radio wavesThe strength of the mice.The weight of the mice.Whether the mice live or die.23. Which of the following can cause pollution?I: Litter and rubbishII: Harmful chemicalsIII: Human wasteIV: Biodegradable materialsI, II and III onlyI, III and IV onlyI, II, III, and IVIII and IV only24. What type of organism eats plants and animals? carnivoreomnivoreherbivorenone of the above25. What does the above picture show?MutationFood webFood chainParasitism26 out of 25Time is Up!
