Prime decomposers are bacteria or fungi, though larger scavengers also play an important role in decomposition if the body is accessible to insects, mites and other animals. Additionally, [ 3 ] soil animals are considered key regulators of decomposition at local scales but their role at larger scales is unresolved.
The primary decomposer of litter in many ecosystems is fungi. [11] [12] Unlike bacteria, which are unicellular organisms and are decomposers as well, most saprotrophic fungi grow as a branching network of hyphae. Bacteria are restricted to growing and feeding on the exposed surfaces of organic matter, but fungi can use their hyphae to penetrate ...
A fresh pig carcass. At this stage the remains are usually intact and free of insects. The corpse progresses through algor mortis (a reduction in body temperature until ambient temperature is reached), rigor mortis (the temporary stiffening of the limbs due to chemical changes in the muscles), and livor mortis (pooling of the blood on the side of the body that is closest to the ground).

The microbial decomposers assimilate the monomers (3) and either mineralize these into inorganic compounds like carbon dioxide or ammonium (4) or use the monomers for their biosynthetic needs. N mineralization leads to a loss of ammonium to the environment (5), but this process is only relevant if the organic matter has a low C:N ratio.

Using crafting with paper products, [3] the Engelman siblings explore "weird but true" things about a broad-range of subjects, mostly focusing on science. They interview experts and travel to locations such as crime labs, amusement parks, and the Everglades to find answers to their questions and discover weird but true facts, often having their experts share their favorite one.
Jeffrey Vinokur was born in 1990 to Russian immigrant parents. He attended Montvale Public Schools. [18] His early interest in science was fueled by doing kitchen science experiments in elementary school, which later progressed to creating a chemistry lab in his parents' garage at age 14, where he would do amateur experiments like making sodium metal from household supplies.
