At the very center of the rain forest food web sit the top, or apex, predators. In most rainforests, these central slots are held by the big catsâtigers, leopards and jaguarsâthe big snakes, the big crocodilians and the largest birds of prey. But even among these apex creatures there is never a truce.ut spiders themselves can fall victim to insects in the form of wasps and army ants. And while itâs easy to imagine rain forest birds eating spiders, it is also true that at least one species of spider in the rainforest food webâthe Goliath trantulaâeats birds. (See a short video on the Goliath here .).
In mathematics, symmetry has a more precise definition, that an object is invariant to a transformation, such as reflection but including other transforms too. Although these two meanings of symmetry can sometimes be told apart, they are related, so they are here discussed together.
(3) Symmetry, in the general sense, means the invariance of the structure of a mathematical or physical object with respect to transformations of the object. For example, the symmetry of the laws of the theory of relativity is determined by their invariance with respect to the Lorentz transformations.1) A symmetry, in the narrow sense, is a reflection with respect to a plane Î± in space or with respect to a line a in the plane. Such a symmetry is a transformation of space or the plane that takes every point M into a point Mâ such that the line segment MMâ is perpendicular to Î± or a and is divided in half by Î± or a.
