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.
Symmetry comes from a Greek word meaning 'to measure together' and is widely used in the study of geometry.Mathematically, symmetry means that one shape becomes exactly like another when you move it in some way: turn, flip or slide.For two objects to be symmetrical, they must be the same size and shape, with one object having a different orientation from the first.here can also be symmetry in one object, such as a face. If you draw a line of symmetry down the center of your face, you can see that the left side is a mirror image of the right side. Not all objects have symmetry; if an object is not symmetrical, it is called asymmetric.
