Answer :
Identifying each term and its definition we find that:
- Extinction: Moccurs when an entire species cannot adapt to a long-term environmental change.
- Migrate: A population that cannot find food after a flood in the environment may in order to survive.
- Speciation: Over many generations, the build up of favorable adaptations in a population may lead to.
When does extinction occur?
The moment of extinction is generally considered to be the death of the last individual of the species. In reproducing species, extinction of a species is usually inevitable when there is only one individual of the species left, or only individuals of the same.
How does animal migration work?
Animals migrate through floating, swimming, walking and flying. This last type of displacement, which can cover half the globe, requires stamina and skill to navigate. Some species are solitary migrants, while others move in groups, small or large, at night or during the day.
What is speciation example?
Allopatric speciation occurs when two populations of a species are separated by a geographic barrier. This geographic barrier, which can be a mountain, a desert or a forest, for example, causes a spatial separation (allopatry). In this case, we say that there was a geographic isolation.
