Question

Ecology - Describe how environmental changes may produce behavioral, physiological, morphological, or adaptive responses in organisms?

Answer 1

Environmental changes (such as a natural disaster) may cause adaptive responses in organisms, such as the Galapagos finches. Due to the islands getting hard-hit by natural disasters, the once-same species of finch were isolated in separate islands. Each generation, through natural selection, adapted to their new environment. For example, their wingspans differed, and their beak shape adapted to their source of food in their separate environments (ranging from big beaks for seeds to narrow beaks for insects).
