(04.01 MC) A species of marine snails have either solid or striped shells. Scientists found that 37 percent of the snail population was striped, and 63 percent was solid. Sea birds are the main predator and when scientists studied their diet, they found that the birds ate more striped snails than solid snails. What could scientists conclude about the snails? (3 points)
