In order to predict how much tension a muscle can produce when contracting, it is important to consider the ______ relationship
serg [7]

The muscles are composed inside mainly of fibers, filaments and proteins, where it is important to consider the <u>length-tension</u> relationship of the thick and thin filaments to know the tension.

<h3>What is muscle contraction?</h3>

It is an organized and natural event that takes place at the level of the muscles when the fibers and proteins inside them come together, and tension is produced in the area.

<h3>Characteristics of muscle contraction</h3>

  • In a muscle contraction, a tension is generated that depends on the length-tension relationship, which causes a displacement of the muscle filaments.

  • The proteins actin and myosin join together, and a force is generated so that the final movement is achieved.

  • To know the tension, the muscle changes length and measurable external work is produced from the force and distance traveled.

Therefore, we can conclude that the contraction allows us to make movements to reach and carry our extremities to different places.

1. in an ecosystem with four levels—producers, primary consumers, and two higher-level consumers—describe where the decomposers
attashe74 [19]
Decomposers, as the name suggests, decompose dead plants or animals into simple compounds. They feed on dead producers from the first levels or consumers from other three levels. Breaking them down, decomposers release nutrients that producers can use.
In an ecosystem with four levels, the first level are producers, such as plants and algae. On the second trophic level, there are primary consumers, herbivores that eat plants, for example, a deer, a rabbit, a grasshopper. The next trophic level belongs to secondary consumers that eat herbivores, for example, a wolf, a fox. The highest level is tertiary consumers that eat carnivores, for example, a bear, an eagle.
