Explanation / Answer

Q) What problems arise when a species is introduced from a foreign ecosystem? How do these problems occur?

Ans) Introduction of foreign species becomes a problem for the native species of the ecosystem.

When a species is introduced from a foreign ecosystem then many types of problems comes up for the native species. Out of the many, one of them is the competition for food. Foreign species starts to compete with the native species for food and other resources, which results in the decline of the population of the native species. Also the foreign species can be dangerous for the native species because they have not evolved together so theor habits and the way of living differ so directly there is a competion for all the things, like food, shelter and other resources.

One more threat that develops is for those species which are dependent on the native species but this threat or this competition is indirect, because whatever the effect this foreign species will have on native species, that would be carry forwaded to the dependent species.
