Answer:

see below :)

Explanation:

Infectious are more easily spread nowadays becuse of an increased population. The more the population increases, the bigger the advantage an infectious disease has. As of right now, because everyone is wearing masks, their immune systems are being weakened. Another reason for this is because of the increase in chemicals in our foods, which are now being transferred to our bodies. All of the medications people are taking also have an affect on the spread of disease; it gives diseases a chance to mutate.

The principle of competitive exclusion states that two species cannot occupy the same niche.

<h3>What is competitive exclusion?</h3>
  • Two species cannot coexist in the same ecological niche for very long without one becoming extinct or being driven out because of competition for limited resources.
  • In Britain, the red squirrels have displaced the grey squirrels as an example of competitive exclusion.
  • Due to diseases, competitive exclusion, and the elimination of hazelnuts, there were fewer red squirrels.
  • Red squirrels were eventually displaced by gray squirrels, who quickly adjusted to their surroundings.
  • Two species with identical niches cannot survive indefinitely, according to the "competitive exclusion principle" (CEP).
  • According to the competitive exclusion principle, only one conclusion is feasible when two competing life forms try to inhabit the same niche: One of them will extirpate the other.
