All of your answers should be recorded on the Eco71-4 Response Sheet you have been given. Supporting Science Textbook Content while enriching the Learning Process in Junior High/Middle School

ECOLOGY ECOLOGY - 1.The malaria problem facing the Dyak people of Borneo was addressed by using DDT to kill the malaria-carrying mosquitoes. Who’s bright idea was this? A. NATO (North Atlantic Treaty Organization) B. WHO (World Health Organization) C. WDCC (World Disease Control Centre) D. CDC (Centre for Disease Control) 2.The DDT also killed a parasitic wasp. This was unfortunate, because the wasps were needed to keep this population under control... A. rats B. cats C. geckos D. caterpillars

ECOLOGY ECOLOGY - 3.The organization that contributed to the first problem, actually made it worst by parachuting these in to the infested area.... A. Live cats B. Super rats C. Flying geckos D. Malaria-eating bacteria 4.DDT negatively affected the population of Bald Eagles. When it entered the water system it was in a concentration of ppm. When the Bald Eagles ate fish further up in the food chain, the DDT concentration had increase to 25 ppm. The DDT concentration had increased about … A. 10,000 times B. 100,000 times C. 1, 000, 000 times D. 10, 000, 000 times

ECOLOGY ECOLOGY - 5.The reason the Bald Eagle population declined was the same reason the Peregrine Falcon population declined. The DDT caused … A. infected habitats B. soft egg shells C. featherless young D. nerve damage 6.Extinction occurs when no individuals of a species are left … A. in a particular area B. anywhere in the world C. In a specific ecosystem D. In a controlled area

ECOLOGY ECOLOGY - 7.Ginseng is a natural root that is used to improve the human immune system. Because of its widespread and increased use as a medicine, it has been added to the list of living organisms that is Extinct, threatened or endangered in Canada. Ginseng is listed as … A. extinct B. extirpated C. endangered D. threatened 8.The Pemberton potato is respected internationally because it is … A. very large B. tasty C. disease free D. easily harvested

ECOLOGY ECOLOGY - 9. Scientist and researchers study the life cycles of insects so they can better control them … A. teach them tricks B. without using pesticides C. and lengthen their overall life span D. to use as food for other research animals 10.

Recovery programs developed to help rescue populations of the Peregrine Falcon were called … A. Captive Breeding B. Controlled Habitat C. Tag and Monitor D. Search and Rescue

ECOLOGY ECOLOGY The recovery program was so successful with the Peregrine Falcon that their status on the COSEWIC list was downgraded from … A. extinct to endangered B. threatened to endangered C. threatened to released D. endangered to threatened 16. High cliffs are natural nesting spots for peregrine falcons, but when they are release close to a city, the Peregrine Falcons will build nests on… A. Playground structures B. Ledges of tall buildings C. Elevator shafts D. Chimneys and Smokestacks

ECOLOGY ECOLOGY Ultraviolet radiation comes to us from space. The primary source of this radiation is the Sun. Luckily for living organisms on our planet, most of this deadly radiation doesn’t reach us, because it is … A. absorbed by oxygen in the atmosphere B. released as a by-product of ozone C. bounced off our atmosphere into space D. resistant to our atmosphere 18. The case of the golden toad is one in which scientists and researchers have no idea about. What are they puzzled about? A. The change in colour B. The toad’s resistance to disease C. The disappearance since 1988 D. The lack of webbed feet it has developed

ECOLOGY ECOLOGY Scientists believe they know what has happened, with certain amphibian populations, around the world. The top 4 theories include: A. Global warming, thinning of the ozone, pollution, earthquakes B. Disease, climate change, pollution, volcanic activity C. Climate change, thinning of the ozone, pollution, disease D. Volcanic activity, hurricanes, pollution, climate variation 20. Wildlife overpasses and underpasses were completed in Banff National Park in This project was designed to help prevent ‘road kill’. Wolf populations in the Banff Park … A. only use the underpasses B. only use the overpasses C. don’t use either type of walkway D. use both types of wildlife walkways
