Answer: b. birds have beak adapted to break open hard shells.
Birds in the rain forests are adapted to perform different functions. It helps birds to capture their food, groom their features, defend their territories and attack predators. The shape of the beak defines a particular ecological niche of a particular bird. The shape of the beak are specially adapted to eat foods such as seeds, fruits, insects. The beaks becomes hard and pointed in order to break open pods, seeds, fruits available as food source in rain forests. Therefore, adaptation in beak allows birds to feed different types of food and allows them to switch to different sources of food if one source becomes scare in the rain forests.
Organisms like birds have adapted their beak to break open hard shells (b) which would most likely to be found in the rainforest.
Further Explanation:
Adaptation is a process of evolution or change according to the environment. This change can behavioral, physiological or the growth of species in accordance with changes in their environment and habitat.
Behavioral adaptation is the change in the behavior of the species according to their environment in which they can reproduce and survive.
Physiological adaptation is a kind of adaptation in which body responses to external stimuli according to the environment so that the species can survive and reproduce.
Structural adaptation is the adaptation of the change in the structure of species like the growth of beaks in birds, according to their environment so they can survive and chance or their survival increases with those conditions.
Birds living in the rainforest have developed structural adaptation that aid in their survival as they have beaks adapted to break open hard shells so they can survive better and reproduce.
