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.
Explain to the student that a line of symmetry is an imaginary line that divides a figure into two congruent parts, each of which is the mirror image of the other. Provide the student with a mirror. Have the student use the mirror to determine if a line drawn is actually a line of symmetry. Provide additional practice through a symmetry sort. Provide the student with two-dimensional figures (some with lines of symmetry and some with lines drawn that are not lines of symmetry).
