Answer: c. Insects have predatory relationships with trees, rather than mutually beneficial ones.
Predation refers to the killing of one organism by another organism in order to obtain food. Mutalism is a relationship between the two living species which lives in close association, in this relationship both the species receives the benefit.
The insects although usually show predatory relationship with the trees and they feed on the leaves, barks and fruits of the trees, they lay their eggs on the barks, leaves, flowers and fruits of the trees. The overall life cycle of insects is dependent on the trees. But the insects may also live in the mutalistic relationship with the trees. In return of the favors insects receive from the trees the insects helps in seed dispersal, this allows the germination of new plants, therefore, colonies of a particular species of trees develop in the region. The insects colonize on the internal as well as on the external surface of the trees and hence, provide them protection against the grazing herbivores animals. Butterflies, bees and other insects sucks the nectar from the flowers of the trees and pick up the pollen and causes pollination, which facilitates in fertilization and reproduction in flowers.
On the basis of the above information, the statement insects have predatory relationships with trees, rather than mutually beneficial ones is false.
