Which pattern is found in the graph?

• The populations do not show a similar pattern

• The populations cycle opposite of each other about every 10 years. When one increases, the other decreases

• The populations cycle with each other about every 10 years. When one increases, the other also increases

Snowshoe hare populations typically increase first. Choose the statement that would BEST explain why.

• The snowshoe hares increase because more plants grow in the summer for them to eat

• The snow shoe hares increase because they cannot survive the harsh winters
