The disease is caused mainly because of the attack on the myelin sheath by own immune system.

Explanation:

The MS or multiple sclerosis refers to a possibly disabling disorder of central nervous system. In the condition, immune system fights against and destroys the myelin, that is, the protective sheath, which envelopes the nerve fibers. This causes problems of communications between the brain and the entire part of the body. Ultimately, the disease can result in deterioration or permanent destruction of the nerves.

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.

i think the answer is gold im not entirely sure
