Type of break is cervical and lumbar curvatures.
If there are no ossification centers, there are no osteoblasts, no osteocytes, no spongy bone, which in turn means no compact bone thus no flat bones which serves as a protection layer.
Osteoclasts are large bone cells with up to 50 nuclei. They remove bone structure by releasing lysosomal enzymes and acids that dissolve the bony matrix. Intramembranous ossification directly converts the mesenchymal tissue to bone and forms the flat bones of the skull, clavicle, and most of the cranial bones. While bone resorption is performed by large immune cells called osteoclasts, osteoblasts, a type of specialized connective tissue-related cells, is responsible for making new bone.

improved soil fertility
Explanation:
One direct benefit of biodiversity is improved soil fertility. Biodiversity is the variety of plants and animals living in a particular ecosystem.
A soli is made up of organic matter. Organic matter is the remain of dead and decaying plant and animal materials in the soil.
Organic matter is a very important soil component.
Since plants and animals eat up plants which takes nutrients from the soil, there must be a way to replenish these vital soil materials.
The more biodiverse an ecosystem, the better its chance of adding more nutrients to the soil as they decay.
