Answer
Note: For full credit, responses must include an explicit statement of the effect on
BOTH the mice population and the wheat plants. Partial credit is given for
responses that refer to one but not both of these.
Correct Response
A. States that mice (population) will increase AND wheat plants will decrease.
Examples:
The population of mice would increase because there are no snakes. The increase
in mice would then cause the amount of wheat plants to decrease.
Then we would get more mice and less wheat plants.
B. States that the mice would eat more (all) of the wheat plants AND that the
mice (population) will decrease as the wheat decreases.
Examples:
Mice would eat all the plants, then the plants would die out, then the mice would
not have anything to eat so then they would die.
Mice would become overpopulated and eat all the wheat. Then all the mice would
starve because there is no food left.
Partial Response
A. States only that the mice will increase.
Examples
The number of mice would increase because there are no snakes to eat them.
There would be lots of mice.
B. States only that the mice will eat more (all) of the wheat plants ( or similar)
Examples
If people killed the snakes the mice would destroy all the wheat plants.
Incorrect Response
A. Refers to an effect on the whole community (ecosystem) but too vague to
interpret.
Examples:
The whole community will be affected.
The ecosystem would be unbalanced
