Habitat loss is perhaps the greatest threat to organisms and biodiversity. [40] Temple (1986) found that 82% of endangered bird species were significantly threatened by habitat loss. Most amphibian species are also threatened by native habitat loss, [41] and some species are now only breeding in modified habitat. [42]
Necrosis is caused by factors external to the cell or tissue, such as infection, or trauma which result in the unregulated digestion of cell components. In contrast, apoptosis is a naturally occurring programmed and targeted cause of cellular death. While apoptosis often provides beneficial effects to the organism, necrosis is almost always ...

Angular misalignment loss, power loss caused by the deviation from optimum angular alignment; Bridging loss, the loss that results when an impedance is connected across a transmission line; Coupling loss, the loss that occurs when energy is transferred from one circuit, optical device, or medium to another
These diseases are oftentimes discussed together, but are distinctly separate conditions of malnutrition. Kwashiorkor is marked by an array of metabolic disturbances of uncertain cause. In contrast, marasmus is more clearly an energy deficiency syndrome, marked by weight loss.
Rice blast causes economically significant crop losses annually. Each year it is estimated to destroy enough rice to feed more than 60 million people. The fungus is known to occur in 85 countries worldwide [ 15 ] and as of 2003 [update] was the most devastating fungal plant pathogen in the world.
