How does resistance training prevent osteoporosis?
Lunna [17]
  <span>It stimulates the bone tissue to grow more dense. Resistance training puts additional stress on the entire body -- our bones aren't just stagnate pieces that we grow once and they forever are the same. They are living tissue and are constantly regenerating themselves. 

With sedentary lifestyles (common today) the tissue becomes weak because it isn't stimulated under load. Much like getting 'out of shape' or losing muscle mass, strength, size. The muscles respond by stimulation (resistance) and thus adapt to compensate. Our bone tissue operates under a similar principle. 

In fact with Calcium supplementation, Vitamin D (supplementation and in some cases increasing direct sunlight per week), with resistance training can *reverse* some osteoporosis? 

How, well.. bones that are ostenopic have become somewhat brittle (of course there are many varying levels of this degeneration..) -- but at any rate they become thinner, less dense, and generally less structurally sound. When you add the nutrients and just as importantly the increasing load that wasn't there before (resistance) they *over time* will react and grow more dense, stronger, and healthier. 

This leads to overall better health, strength,.. and a MUCH less likely chance to fracture as a result of osteoporosis.</span>

Can somebody give me description of the role of these decomposers i'm going to list below:
Lynna [10]

Answer:

- spiders

they break down organic material that then provide nutrients for the entire food web.

- freshwater shrimps

Animals like shrimp and crabs can break the materials down to detritus. Then bacteria reduce the detritus to nutrients.

-moss

Moss is considered both a producer and a decomposer because it produces its own food through photosynthesis and helps to break down organic matter into nutrients. ... In the forest, moss carpets the floor and fallen organic matter such as rotting logs. The moss helps to decompose the logs and recycle the nutrients.
