All species have a tolerance limit before they are no longer well suited to live in their environment. In three to five sentences, discuss the potential outcomes for a population when that limit is reached. There are at least four possibilities, and one point will be assigned per potential outcome mentioned.

When a population reaches its tolerance limit in its environment, one potential outcome is a decline in population size due to increased mortality rates. This could lead to decreased genetic diversity and increased competition for resources among individuals. Another potential outcome is the migration of the population to a more suitable environment, if one is available. If the population is unable to migrate or adapt to the environmental changes, extinction is also a possible outcome. Overall, reaching the tolerance limit can have detrimental effects on the population's long-term survival and success.
