Ecological relationship. An ecological relationship is the relationship between an organism in its ecosystem. All organisms in an ecosystem are connected in one way or another. Each interaction depends on the one before it. Each population interacts with one another in a complex web of relations. Ecological relationships help better to describe how they are connected. There are ecological relationships in which two are oppositional and four are symbiotic. The oppositional relationships are predation and competition. The
Raw Materials. There are six types of asbestos: actinolite, amosite, anthophyllite, crocidolite, tremolite, and chrysolite. The first five types are known as amphiboles. They are characterized by having very strong and stiff fibers, which makes them a serious health hazard.
Asbestos can be divided into two basic groups, serpentine and amphibole, which differ in their physical characteristics. Serpentine asbestos develops in a layered or tiered form, whereas amphibole asbestos has a chain-like structure. Identification. Asbestos is generally made up of fiber bundles which easily separate into long, thin fibers. Positive identification of a specific fiber type requires microscopic analysis and examination. All asbestos fibers are hazardous to human health. Asbestos Types. There are six types of asbestos minerals that occur naturally within the Earth's environment. The Environmental Protection Agency (EPA) has classified the types as such: Chrysotile: Chrysotile is one of the most common and most dangerous forms of asbestos found within our Earth.
