The correct answer is 3- <span>The smelt and alewife may out-compete the native fish by consuming all of the zooplankton.
The diagram tells us that zooplankton is eaten by smelts and alewifes. If these two species increase in number, less of the zooplankton will be left for plankton-eating fish, which is a native type of fish, to eat.
</span>
<span> smelt and alewife eat most of the existing plankton so, they are out-competing the native fish.</span>
Natural selection states that the most advantageous trait in a species will become more common in the population, and can even replace other non useful trait over time. That is evolution by natural selection. In the case of anteaters, these animals became better adapted to the environment by growing a longer snout to have better access to food (ants).
