Composting |
As part of a class exercise on composting, two students constructed
identical worm bins (containers), which they kept at their homes. Red worms were then added to the
bins. Both students counted the number of red worms in their bins on the first of the month. The
results are shown in the graph below. | |
A worm bin should
be kept between 12°C and 25°C and 2.5 kg of food should be added to a bin each week.
Student 1 followed these requirements exactly. During December, Student 2 left town for three weeks;
during March, the temperature in Student 2's worm bin reached
30°C.
| |
|
|
|
7.
|
The
highest population density of red worms in Student 2’s bin was reached at the beginning
of a. | November. | c. | March. | b. | December. | d. | May. | | | | |
|
|
|
8.
|
It
was hypothesized that there was a maximum number of red worms that could survive in the worm
bins.
Is this hypothesis supported by the data in the
graph? a. | Yes, because the
number of red worms in Student 1’s bin remained fairly constant between December and
May. | b. | Yes, because the
number of red worms in Student 2’s bin continued to increase between September and
May. | c. | No, because the
number of red worms in Student 1’s bin decreased between December and
May. | d. | No, because the
number of red worms in Student 2’s bin decreased between December and
January. | | |
|
|
|
9.
|
Which
of the following probably accounted for the large drop in population in Student 2’s bin
from March to April? a. | overpopulation | c. | lack of food | b. | overheating | d. | lack of
water | | | | |
|
|
|
10.
|
Suppose several houseflies were allowed to enter the worm bins and feed on the food
scraps. Which of the following interactions would most likely occur between the houseflies and
the red worms? a. | predation | c. | competition | b. | parasitism | d. | commensalism | | | | |
|
|
|
11.
|
Are
the systems established in the compost bin self-sustaining? a. | No, because the
red worms did not reproduce. | b. | No, because the students need to provide energy to the systems
in the form of food. | c. | Yes, because once the compost bins were established, the
students did not have to add anything else to them. | d. | Yes, because the
red worms reproduced. | | |

Aristotle thought that a moving object would stop because its natural state was to be
at rest. Newton thought that friction is a force that opposes all motion and eventually stops moving
objects.
Suppose you were coasting on a level surface on a
bicycle and there was NO friction. What would happen to your speed, according to Aristotle and
Newton? a. | Aristotle: slow
and stop; Newton: slow and stop. | b. | Aristotle: maintain speed; Newton: slow and
stop. | c. | Aristotle: maintain speed; Newton: maintain
speed. | d. | Aristotle: slow and stop; Newton: maintain
speed. | | |
