NGSS.MS-LS4-4

A yellow morph and green morph of an insect lives in the rainforest canopy. You would expect:

• the green population to increase and the yellow to decrease

• both populations should stay the same

• both populations will increase

• the green population to decrease and the yellow to increaseThis is a wrong answer
