The diagram below shows the feeding relationships between populations of organisms in an area. The arrows point from the organisms being eaten to the organisms that eat them.
Using only the the relationships between the organisms shown in the diagram, if most of the butterflies are killed, which of the following statements describes what will happen to the number of lizards and why? (SC.7.L.17.1)

The number of lizards will increase because there are fewer butterflies to eat them.

The number of lizards will decrease because there are not enough butterflies for them to eat.

The number of lizards will stay the same because the butterflies are not eaten by the lizard.

The number of lizards will stay the same because a change in the population of butterflies will not affect any other population of organisms.
