The ground level of a forest is quite dark because the leaves of the tall trees block out most of the sunlight. Plants at the ground level compete for sunlight as well as for water and mineral resources. One population of plants growing under the trees has a variation in its leaves. Which statement explains a variation in the leaves that affects the plants’ probability of surviving at the ground level of this forest?
