To understand osteoporosis, it is helpful to understand the basics of bone formation. Bone is living tissue that is constantly being renewed in a two-stage process (resorption and formation) that occurs throughout life. In the resorption stage, old bone is broken down and removed by cells called osteoclasts.
The grassland biome. As the name suggests, these are massive areas dominated by one or a few species of grass, with a few. sparsely distributed trees. There are two main types of grassland biomes: the Savanna Grasslands and the Temperate Grasslands.One major savanna is located in Africa, and takes up more than a third of. the continents land area. Others can be found in India, South America and Australia.s the name suggests, these are massive areas dominated by one or a few species of grass, with a few. sparsely distributed trees.

Grassland biomes are large, rolling terrains of grasses, flowers and herbs. Latitude, soil and local climates for the most part determine what kinds of plants grow in a particular grassland. A grassland is a region where the average annual precipitation is great enough to support grasses, and in some areas a few trees. The precipitation is so eratic that drought and fire prevent large forests from growing. Grasses can survive fires because they grow from the bottom instead of the top.
