Land area of the Earth occupied by the forest (including tropical, moderate, boreal) is: about 25% 31. Inaustrles contrl ute o D t na tat damage ana use proper drainage system produce freons plant trees organize natural parks and reserves 32. The primary cause of species extinction is: destruction of habitats exposure to hazardous waste biological magnification acid rain global warming 33.

Biological magnification is the process of: oestructlon I T tney: pollute water increasing concentration of hazardous wastes through food chains concentration of alcium deposits in the shells of dead organisms algal bloom in a lake accumulation of organics in the water reservoirs biogeochemical cycles 34. To prevent or reduce waste it should be done: to use recycled materials whenever possible to transport hazardous waste rather than treating on-site to use over-packaging to avoid using a catalytic converter to release waste into the domestic sewage system 35.

The main physical reason of the photochemical smog is: atmosphere temperature inversion wind speed mixing between air layers atmosphere gas composition precipitation 36. The major component of photochemical smog is: ropospheric ozone sulfur dioxide particulates carbon dioxide 37. The primary reason of acid rain is: burning fossil fuels wood cutting ozone layer depletion marsh drainage water thermal pollution 38. Acid rain is harmful because it can: dissolve nutrients and toxic metals in the soil cause skin cancer in humans cause land flooding destroy ozone layer Increase eart n temperature 39.

The pH of acid rain is: below 5 below 6 below 7 below 8 below 9 40. Acid rain occur as: rain, snow, mist, fog, hail only rain acetic acid lemon acid carbonic acid 41 . The chemical compounds that can cause acid rain: sulfur dioxide and nitrogen oxide cetic and carbonic acid methane and ammonia carbon monoxide and carbon dioxide ozone and particulates 42. Loss of ozone has serious effects in people because ultra-violet radiation can cause: skin cancer and eye damage liver and kidneys damage respiratory and nervous system damage hepatitis and heart attack anemia and diarrhea 43.

To stop ozone layer depletion it should be done: to replace or recycle freons used in fridge and cooling systems to stop wood cutting to use solar power to use a nuclear power to use geothermal energy 44. The heights of troposphere and stratosphere above the earth: 0-15 km and 15-55 m respectively 0-5 km and 5-50 km respectively 0-10 and 10-80 km respectively 0-12 and 12-100 km respectively 0-20 and 20-200 km respectively 45.

The greenhouse gases are the following: C02, CFCS, CH4, NO, N02, troposphenc ozone stratospheric ozone NH3, 02, noble gases chlorine and fluorine S02, N02, NO, CO 46. Alternative sources of energy include: sun, wind and waves natural gas, peat and tides 011, coal ana geotnermal energy biomass, nuclear energy and oil oil, coal, and natural gas 47. To reduce greenhouse effect it should be done: to use alternative sources of energy to avoid sewage water o burn the trees and rubbish to cut off rain forest to use fertilizers 48.

Distribution of gas concentrations in the atmosphere in descending order is: nitrogen – oxygen – argon – carbon dioxide carbon dioxide – oxygen – nitrogen -argon oxygen – argon – nitrogen – carbon dioxide argon – nitrogen-carbon dioxide – oxygen oxygen – carbon dioxide- nitrogen – argon 49.

The global warming is primarily caused by: increase of greenhouse gases concentration increase of tropospheric ozone decay of the organic compounds increase of chlorofluorocarbon (CFCs) concentration use of alternative kinds of energy 52. Herbicides are chemicals that can control population growth of undesirable organisms such as: plants worms fungi insects bacteria 53.

Factors that specifically cause abnormalities during embryo development are called: teratogens mutagens fungicides 4. Organic garbage that is a subject to decay by microorganisms is called: DloaegraaaDle 100% recycled renewable nonbiodegradable 55. Renewable resources include: humus coal natural gas minerals 56. Nonrenewable resources include: soil wildlife forests phytoplankton 57. The main characteristic of biomass pyramids of freshwater or marine is to be: inverted right depends on a particular ecosystem do not change changes cyclically 58.

According to number pyramids, a quantity of organisms at a higher trophic level: decreases increases 59. Amount of energy passing from one trophic level to the next one is: 10% 00% 25% 1% 60. Consumers, such as humans, that obtain their nutrients by eating both producers and other consumers are called: omnivores carnivores herbivores scavengers autotrophs 61 . Consumers, such as wolves, that obtain their nutrients by eating other consumers are: carnivores omnivores autotropns 62. Consumers that obtain their nutrients by eating producers are: herbivores 63.

The wolf and the fox are on the same trophic level because both animals: eat herbivore organisms live on the land use food at 10% have large size have similar behavior 64. Autotrophic organisms are: plants birds reptiles 65. Heterotrophic organisms are: jellyfish chemosynthetic bacteria photosynthetic bacteria phototrophs 66. Organisms that use ready food are called: heterotrophs chemotrophs producers 67. Nitrogen in the atmosphere is captured by: nitrogen-fixing bacteria nitrifying bacteria denitrifying bacteria 68.

Primary productivity is the energy contained in the trophic level of: producers decomposers 69. Plants in an ecosystem play the following role: synthesize organic substances from inorganic compounds are primary consumers decompose organic substances to inorganic compounds are secondary consumers are decomposers 0. Define the right order of components in the trophic chain “tree producer – primary consumer – secondary consumer heterotroph – primary consumer – secondary consumer autotroph – heterotroph – decomposer producer – heterotroph – decomposer producer – consumer – decomposer 71 .

The following is Not correctly matched: herbivore – autotroph heterotroph – consumer phototroph – plants carnivore – animals bacteria – decomposer 72. The major producers found in aquatic ecosystems are: aquatic plants zooplankton benthos – hare- fox”: 73. Two species that occupy a very similar niche are likely to be: competitors ommensalists mutualists predators parasites 74. An interaction between two species in which species benefit each other is: mutualism parasitism competition predation commensalism 75.

Type of biotic relationship when one species benefits and other one has neither harm nor profit: commensalism 76. Example of interspecific competition is relationship between: black cockroaches and red cockroaches thinning fur trees out in a population organism-host and worms-parasite wolves in a pack some mushrooms and trees 77. Competition, predation, and symbiosis are all types of: biotic relationships
