Numbers

Numbers are our way to quantify, label, and organize the world around us in a logical manner. However, the systems used to obtain this goal differ geographically, historically, and by relative utility. All questions pertaining to numbers, including historic labeling systems, bases of numerical systems, constants, and the various ways they're grouped together, should be placed into this category.

How do you do a roundoff?

User Avatar

Asked by Wiki User

To be able to perform a roundoff it is necessary to be able to do a cartwheel. Next practice a cartwheel from a hurdle step, which means to use a small run and a hop into the "lunge" with one leg forward so the added speed makes the cartwheel rotate faster. The next step is to do a "push away" or 'snap down" cartwheel from the hurdle. The idea is to push off the ground with the arms so that the entire body is off the ground momentarily before the first foot touches the ground. Once a student can do this particular type of cartwheel then turning it into a roundoff is only a matter of finishing the cartwheel with the feet together. The hurdle, and snap down add enough extra time to bring the legs together and make the roundoff possible. A pointer on how to place the hands: Try to consistently place the hands on the ground one at a time and more or less in a straight line. If the fingers are pointed in the direction of where the skill began, this way it is possible for the gymnast to push from the hands as well as the arms, which makes a good amount of difference. Good luck.

Why are the numbers of trophic levels limited?

User Avatar

Asked by Wiki User

At each trophic level in a food chain, a large portion of the energy is utilized for the maintenance of organisms which occur at that trophic level and lost as heat. As a result of this, organisms in each trophic level pass on less and less energy to the next trophic levels, than they receive.
