Request Description
1. Organisms that feed only on plants are called Detritivores Omnivores Carnivores Herbivores Decomposers 2. Which of the following is NOT an example of an indicator species? trout in water with a specifric temperature requirement birds that need a large forested area butterflies that use a specific plant as food frogs that take in water and air though their skin All are example of indicatory species 3. A species in an ecosystem that plays a central role in the health of that ecosystem, and whose removal may cause the collapse of the ecosystem, is called a(n) foundation species indicator species native species keystone species specialist species 4. One way that species evolve over time to reduce niche overlap is called competitive exclusion principle resource partitioning population distribution chemical warfare mimicry 5. Aerobic respiration requires glucose and carbon dioxide. glucose and oxygen. oxygen and water. carbon dioxide and water. carbon dioxide and oxygen. 6. The first law of thermodynamics tells us that Doing work always creates heat. Altering matter is the best source of energy. Energy cannot be recycled. Energy is neither created nor destroyed. Energy cannot be converted. 7. Which of the following is NOT a greenhouse gas? carbon monoxide water vapour carbon dioxide methane nitrous oxide 8. Which of the following is an example of a density dependent population control Parasites Predators infectious diseases competitors with high niche overlap all of these answers 9. If grass stores 1,000 energy units received from sun, the ecological efficiency of the ecosystem is 10%, and the trophic levels are grass > cow > human, how many units of energy does the human receive of the original 1,000 units? 900 200 100 10 1 11. All of the following are part of the freshwater aquatic life zones, EXCEPT lakes mangrove forests inland wetlands streams rivers 12. In terms of habitat destruction, the greatest eliminator of species is pollution of streams, lakes, and oceans destruction of coral reefs destruction of wetlands plowing of grasslands deforestation in tropical areas 13. The term malnutrition refers to people who consume low calories low carbohydrates too much meat low protein, high carbohydrate high protein 14. In lakes, the nutrient-rich water near the shore is part of the limnetic zone benthic zone littoral zone profundal zone abyssal zone 15.

Which of the following is an ADVANTAGEof hydropower? high methane emissions disruption of downstream aquatic ecosystems high-cost of energy large land disturbance large untapped potential 17. Even carefully designed logging roads have harmful effects, including all of the following EXCEPT increased erosion sediment runoff into waterways habitat fragmentation access to farms, mines, and ranches loss of diversity 18. Organisms in this area must be able to avoid being swept away, crushed by waves, or being left high and dry at low tides, and must survive daily on seasonal salinity and temperature changes. Estuaries coastal wetlands bathyal zone intertidal zone coral reefs 19. What can you do to help sustain terrestrial biodiversity? All of the following are things each of us can do, EXCEPT Plant trees and take care of them. Recycle paper and use recycled products. Buy sustainable wood and wood products. Help restore nearby degraded forests or grasslands Do not plant your yard with local plants 20. Late successional plants are largely unaffected by plants at earlier stages of succession, a factor called Facilitation Imperturbability Inhibition Tolerance Intolerance 21. Which of the following does NOT represent kinetic energy? the wind blowing flowing water reservoir behind a dam ocean waves electricity 22. Which of the following is said to occur when one organism feeds on another organism, usually by living on or in that other organism? interspecific competition predation parasitism mutualism commensalism 23. The highest rate at which a renewable resource can be used indefinitely without reducing its available supply is called Conservation Sustainable yield Preservation Recycling All of these answers 24. Scientists classify energy as either chemical or physical kinetic or mechanical potential or mechanical potential or kinetic chemical or kinetic ? 25. Which of the following is NOT an abiotic factor?

The mass number is equal to the sum of the neutrons and isotopes neutrons and electrons neutrons and protons protons and electrons ions and isotopes 28. When plotting the number of individuals in a population against time the data yield a J-shaped curve, which indicates which of the following? logistic growth environmental resistance exponential growth carrying capacity biotic potential 29. Carbon is a major component of water the oceans organic compounds the atmosphere hydrologic cycle 30. Effects of pollution might include being unable to see the top of skyscrapers because of smog destruction of a statue in a city park by acid rain spread of a disease from an open dump fish kills in lakes and streams all of these 31. It is necessary to use energy to get energy. The difference between what you get and what you use to get it is called gain loss gross energy profit net energy 32. The middle, partially melted zone of the interior of the earth is called the crust tectonic plate core mantle magma 33. The greatest marine biodiversity is located in the bottom region of the ocean in the surface region of the ocean in the coastal region of the ocean in the open ocean in coral reefs 34. Which of the following is NOT true about surface fires? They free valuable mineral nutrients tied up in decomposing litter. They release seeds from cones of lodgepole pines. They increase soil erosion. Wildlife requires surface fires to maintain their habitats. They help control diseases.? 35. Global oil production peaks when oil becomes cheap and use increases demand for oil lessens large new proven reserves are located maximum global rate of production is reached OPEC decides to slow oil production 36. The lack of sufficient water to meet the needs of the people in a country or region is called water deficit water shortage drought hydrological shortage hydrologic cycle 37. The term undernutrition refers to people who consume low calorie diet high calorie diet low protein, low carbohydrates low protein, high carbohydrates high protein, low carbohydrates 38. Deep lakes with steep banks that have a small supply of plant nutrients are oligotrophic lakes eutrophic lakes culturally eutrophic lakes hypereutrophic lakes mesotrophic lakes 39.
