Afood chain acts like any system; when one part changes, the rest of the system is effected. which statement best describes a relationship between the organisms in this food chain? a) if the mouse population decreases, the hawk population will increase. b) if the mouse population increases, the seed population will increase. c) if the seed population decreases, the hawk population will remain the same. d) if the seed population increases, both the mouse and hawk population will increase.

D: if mouse food increases (seed) then more mice can survive and if there are more mice then the can also be more hawks.
A is not correct because if the mouse decreases (hawk food) the hawk populations also decrease
B is not correct because seed is mouse food and is the mouse population increases it will eat all the seed and seed population goes down
C is not correct because if the sees population decreases the number of mice will decrease and then there will be less hawk food and hawk will also decrease
