It kills other plants and makes room for it to grow. Birds scatter the fig seeds around the branches of another tree. When the seeds germinate, the roots grow and as they grow longer they grow in twisted shapes around the bark of the other tree right down to the ground. They grow stronger and bigger and slowly crush the bark of the other tree on which they are hanging. The roots of the strangler fig tree then cuts off the food supply of the host.
Bright light attracts nocturnal insects.
This phenomenon is called phototaxis. The strength of the light also influences the movement of the wings of an insect. When the light from a distant source, for instance moonlight in equal intensity reaches both the eyes of an insect, it flies in a straight line with both the wings moving in the same way. But if the light source is closer, for instance a bulb or a candle flame, it is perceived more strongly by one eye than by the other. Bats are mammals that come out at dusk and hunt insects.
