Question 30 of 35
30. Question
During their long migration to Mexico, monarch butterflies depend on the grasslands’ wildflowers for food. However, many of the grasslands they typically encounter have been converted to agricultural use either for grazing herds of cattle or for planting food crops. Others have become urbanized or areas of suburban human habitation. What is most likely the consequence on the monarch butterfly population?
CorrectIncorrect -
Question 31 of 35
31. Question
A teacher purchases 20 goldfish for a class experiment. After the students conclude their experiment, the teacher sets up a fish tank with snails, plants, a substrate, a filter, and other supplies. Over the first week of housing the goldfish, 12 of them die. The 8 remaining goldfish survive in balance with their habitat for the rest of the school year. What is most likely the carrying capacity for goldfish in this aquarium?
CorrectIncorrect -
Question 32 of 35
32. Question
Excess nutrients washing from farms into bodies of water can cause a buildup of algae called eutrophication. Excess algae block sunlight to other producers that live in the water. The algae eventually begin to die and they decompose, which depletes the oxygen in the water. The decreased oxygen levels cause many aquatic animals, like fish, to suddenly die. Eutrophication is an example of a trophic cascade.
CorrectIncorrect -
Question 33 of 35
33. Question
Many industrial processes use water from local sources, such as rivers or lakes, as a coolant. This means that they pump water out of the river, use it to cool down machinery, then return the warmer water back to the river. Most aquatic organisms are adapted to live in a narrow temperature range. When warm water is added to the habitat, it can kill fish and amphibians due to thermal shock. Warmer water is able to contain less dissolved oxygen that aquatic animals need. It can also increase the activity of microorganisms that can cause a buildup of toxins in the habitat. Based on this information, what is the most likely conclusion?
CorrectIncorrect -
Question 34 of 35
34. Question
A toxic pesticide flows from local farms and into water sources. The pesticide is absorbed by small organisms that are eaten by small fish. The small fish are eaten by larger fish. Then, the larger fish swim upstream to spawn (reproduce). There, they are consumed in large quantities by the bear population. Many of the bears that eat these fish experience serious illnesses and die. What can you most likely conclude from this information.
CorrectIncorrect -
Question 35 of 35
35. Question
“The ozone layer is a protective atmospheric layer that surrounds the Earth and reflects most of the harmful UV rays from the sun back into space. In 1985, a massive hole in the ozone layer was discovered by scientists over the south pole. The damage was spreading at an alarming rate due to the use of chemicals called CFCs in consumer products such as aerosol spray cans, refrigerators, air conditioners, and foam insulation. In order to reverse the problem, 180 countries signed an agreement called the Montreal Protocol to make sure that businesses came up with replacements for these damaging products. As a result, the damage to the ozone layer has ceased and it has begun to repair itself. Scientists estimate that the ozone layer may be completely restored by the year 2060.”
Based on this passage, what can most likely be concluded?CorrectIncorrect
