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.
Generally, an object with 'rotational symmetry' also known in biological contexts as 'radial symmetry', is an object that looks the same after a certain amount of rotation. An object may have more than one rotational symmetry; for instance, if reflections or turning it over are not counted.The degree of rotational symmetry is how many degrees the shape has to be turned to look the same on a different side or vertex.herefore a symmetry group of rotational symmetry is a subgroup of E + (m) (see Euclidean group). Symmetry with respect to all rotations about all points implies translational symmetry with respect to all translations, so space is homogeneous, and the symmetry group is the whole E (m).
