People with poorly controlled diabetes are at risk of amputation due to damage of nerves in the extremities of the body. This damage to nerves is caused by chronically high blood sugar. The condition, when it is caused by uncontrolled blood sugar is called diabetic neuropathy.<span>Diabetic neuropathy mostly affects the feet and they lose feeling, such that an affected person cannot sense pain. When they develop an ulcer or small injury to the feet, it may often go unnoticed and with time become infected. High blood sugar impairs the normal healing process and the injury or ulcer may not heal quickly thus compounding the problem. The outcome of this is that the infected part e.g. a toe, may fester and even become gangrenous putting the whole bod at risk and thus the only away to save the rest of the body is removal by amputation.</span>
Answer:
There is no video but ecological relationship will be defined on a general note and it is not always beneficial to organisms.
Explanation:
In an ecosystem, organisms of the same or different species tend to interact with one another. This interaction is referred to as ECOLOGICAL RELATIONSHIP between the involved organisms. An ecological relationship can be of different types depending on the effect.
SYMBIOSIS is an ecological relationship between two organisms that interact together. SYMBIOSIS can either be mutualistic (both organisms benefit), parasitic (one organism loses and one gains), or commensalistic (one organism benefits and one neither benefits or loses). Another ecological relationship is PREDATION, where one organism called the PREDATOR feeds on part or all of another organism called PREY in order to obtain energy.
As stated above, some of the organisms involved in an ecological relationship benefits while others lose. Hence, it is not always a beneficial relationship to organisms.
