• Population Decreased because they could camouflage, they passed on their traits to their offspring

• Population Decreased because they could NOT camouflage, they passed on their traits to their offspring

• Population Decreased because they could NOT camouflage, they did not pass on their traits to their offspring

Based on the image above, which species of barnacle is a better competitor? Species A or Species B?

• Species A, because it grows in all three zones when put together with species B

• Species A, because it outgrows the other in 2/3 zones when put together with species B

• Species B, because because it grows in all three zones when put together with species A

• Species B, because because it outgrows the other in 2/3 zones when put together with species A

Which Plant will better compete for resources and why?

• Plant 1 because it has larger roots to absorb water and grows taller to absorb sunlight

• Plant 2 because it has larger roots to absorb water and grows taller to absorb sunlight

• Plant 1 because it has smaller roots to absorb water and grows shorter to absorb sunlight

• Plant 2 because it has smaller roots to absorb water and grows shorter to absorb sunlight
