The correct answer is D. How migratory patterns change in response to alterations in an ecosystem
Explanation
An ecosystem is a complex system of relationships between the different groups of living organisms and the natural physical environment in which they live. On the other hand, a migration pattern is a migratory trend of some species, that is, a displacement of a community to seek better conditions in the ecosystem to live, reproduce, feed, among others. According to the above, the situation explained in the statement demonstrates how migratory patterns change in response to alterations in an ecosystem because the Blackcaps changed their migration pattern because they used to go from Central Europe to England, changing their destination to Spain in where they found easier ways to get around and get food. So, the correct answer is D. How migratory patterns change in response to alterations in an ecosystem.
