Mangrove trees are common to the Florida Everglades. The tree roots serve as a place for freshwater oysters to attach when the
tide is high, as shown in the picture below. The oysters are
protected from predators when attached to the roots underwater
The oysters do not harm the trees nor do they provide any benefit
to the trees. Which of the following relationships is most similar to
the relationship between the mangrove trees and the oysters?
African ants living in acacia trees feed on leaf-eating
insects found on the tree.
Spider crabs are camouflaged by the green-brown algae
that find a place to live on the crabs' shells.
A whale is unaffected by the attached remora fish
feeding on the whale's leftover food.
Bees fly from one flowering plant to another gathering
nectar and pollinating the flowers.
