Make an observation about the coyote population between year 8 and 9. Use that observation to make an inference explaining the population change.

• The coyote population between year eight and nine decreases by five coyotes. There were not enough mice to sustain the large coyote population so some of the coyotes had starved to death.
• The coyote population between year eight and nine increases by five coyotes. There were not enough mice to sustain the large coyote population so some of the coyotes had starved to death.

• The coyote population between year eight and nine decreases by 10 coyotes. There were not enough mice to sustain the large coyote population so some of the coyotes had starved to death.

• The coyote population between year eight and nine decreases by 15 coyotes. There were not enough mice to sustain the large coyote population so some of the coyotes had starved to death.

What happens to the mice population when there are more than 10 coyotes?(2 points to explain the relationship between the two variables and 1 point to write in complete logical sentences)

• When there are more than ten coyotes, the mice population starts to decrease.
• When there are more than ten coyotes, the mice population starts to increase.

• When there are more than 2 coyotes, the mice population starts to decrease.

• When there are more than 20 coyotes, the mice population starts to increase
