Consider this:

Blackcaps are birds that used to migrate from Central Europe to Spain. Recently, a population of these birds have started to migrate to England. Scientists believe that this new migratory route is because the birds have found food in bird feeders in the gardens of England and because this route does not expose the birds to winter conditions in the Alps. This situation shows:

A) the effects of symbiosis

B) the difference between biotic and abiotic factors in an ecosystem

C) how changes in biodiversity impact an ecosystem

D) how migratory patterns change in response to alterations in an ecosystem

    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.
