Question

Which of the following is (are) likely reasons for the migration of native species from an area?
I. A forest fire destroys a section of forest on the east side of a river.
II. There is increased competition for limited resources.
III. Individuals are separated from the rest of their population.

Answer 1

Answer:

I. and II.

Explanation:

Migration can happen for many different reasons.

A forest fire can destroy a natural habitat, forcing the native organisms to move and relocate, thus leading to migration of a species from area to another.

Increased competition for limited resources can also be a factor. If there is too many predators or too many organisms consuming resources, it may force organisms to relocate to another area, thus leading to migrations of a species from a competitive area to a less competitive area.

Individuals who are separated from the rest of the population isn't a migration. Migration refers to a species group, meaning more than 1 individual is moving from one location to the next due to a factor.
