Answer:
C) The population will stay the same both ways. D) 12 - 32 degrees celsius.
Step-by-step explanation:
C = When the water temperature was 8 and 10 ° C, no plants were grown, seeming as it would stay the same if the water temperature dropped, and the plants seemed to die as they went higher and higher, so the ending number would probably stay the same. D = The plants only grew between the water temperatures 12° C and 32° C.
