Today the island looks much as it did before the eruption. Which statement is the best possibly explanation for this? Altered ecosystems regain stability through the evolution of new plant species Geographic barriers prevent the migration of animals to island habitats Destroyed ecosystems always return to their original state Destroyed environments can recover as a result of the process of ecological succession3. Which of the following would be considered a natural resource? Plastic Rock Steel Concrete4. An example of a producer is: Water Lily Caterpillar Fungus Bird5. Scientists use absolute dating to determine The approximate date of a rock layer or fossil The physical appearance of fossils The chemical composition of rocks The numerical age of an object in years6. A fungus is an example of: A saprophyte An herbivore An autotroph An omnivore7. Which relationship is illustrated by a tapeworm living in the intestine of a human? Commensalism Predator--prey Mutualisms Parasitism8. Lynnette is categorizing natural resources. Which of these is a nonrenewable resource she should include on her list? Solar energy Oil Water Wind9. How does maintaining water quality help ecosystems? It prevents them from becoming deserts. It prevents pollution from poisoning living things It helps hydroelectric power plants make more electricity. It helps freshwater ecosystems obtain more salt water.10. One biotic factors that limits the carrying capacity of any habitat is Activity of decomposers Amount of soil erosion The availability of water Level of atmospheric oxygen11. 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 keeps governments stable. It ensures that resources will not be polluted or used up too quickly. It gives people the opportunity to vote. It prevents people from using resources.12. Which rocks can be changed into sediments by weathering and erosion? Igneous Sedimentary Metamorphic All of these13. The burning of fossil fuels can lead to acid precipitation. What do fossil fuels generate that is needed to form acid precipitation? Particulate pollutants Water Energy Gas pollutants14. Which of the following are non-biodegradable materials?I: WoodII: PlasticsIII:Styrofoam boxIV: Prawn shell II and III only II, III, and IV only I and II only I, II, III, and IV15. Adaptation is one of the parts of natural selection. What is an adaptation? An inherited trait that improves chances of survival and reproduction for a group of individuals in a population A group of organisms that can mate to produce fertile offspring A process by which individuals that are better adapted are more likely to camoflage themselves to their environment A process by which inherited traits in a population change over generations16. The removal of nearly all the predators from an ecosystem would most likely result in An increase in the number of carnivore species A decrease in new predators migrating into the ecosystem An increase in the number of herbivores A decrease in the size of decomposers17. The source of energy for almost all life on earth is: Animals Fungi Sunlight Water18. 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 weight of the mice. The amount of mice exposure to radio waves The strength of the mice. Whether the mice live or die.19. Tectonic plates may move because of convection currents that occur in the mantle. What is convection? The transfer of energy through materials in direct contact. The transfer of energy as earthquake waves. The process that breaks down rocks. The transfer of energy due to the movement of matter.20. Several factors can lead to soil erosion. Which of these human activities is most likely to contribute to soil erosion? Reducing the amount of livestock in an area Clearing land for farming Planting trees and vegetation Designating land as a wildlife habitat21. Insecticides and weedkillers will cause no harm to marine life. false true22. Two closely related species of birds live in the same tree. Species A feeds on ants and termites, while Species B feeds on caterpillars. The two species coexist successfully because They interbreed Each occupies a different niche They use different methods of reproduction They live in different habitats23. Which of the following activities does not have a negative impact on the environment? Using weedkillers for farming Burning of fossil fuels Increasing the use of chlorofluorocarbons Planting trees in a nature reserve24. Which of these food chains is in the correct order? Water lily, caterpillar, frog, snake Water lily, frog, caterpillar, snake Snake, frog, caterpillar, water lily Caterpillar, water lily, frog, snake25. Eutrophication refers to a process of change that takes place in a body of water. Which of the following causes eutrophication? Additional Nutrients Thermal Pollution CFCs Acid rain26 out of 25Time is Up!
