And all the dark nether regions untouched by the circulatory system are filled up with the same chemicals. Meaning, a killer could throw off police by posing the victim, causing different lividity patterns. The high temperature and moisture of tropical rainforests cause dead organic matter in the soil to decompose more quickly than in other climates, thus releasing and losing its nutrients rapidly. Acidification slows the growth of fish and shellfish and can . Eutrophication is most often the result of human activity. During the fragmentation process, the breaking of detritus into little pieces by detritivores. Thus, the correct answer is Fragmentation: Carried out by organisms such as earthworm. Natural sources of organic matter include plant decay and leaf fall. The skeleton, in addition to providing support for the body, serves as a large store of calcium and phosphate in the form of crystals called hydroxyapatite, which has the formula Cajo(PO4)6(OH)2. Decomposition consumes a lot of oxygen, so when the decomposition of algae (or any other organic waste for that matter) happens beneath the surface of the water, often oxygen is consumed faster than it can be replenished. Step 2: Oxygen radicals then react with molecular oxygen to . Dead zones occur in coastal areas around the nation and in the Great Lakes no part of the country or the world is immune. Though we call them needles, the green of pines and other evergreens are actually leaves.
