Answer 1

Answer:

c.the impact of removing or adding organisms to an ecosystem

Explanation:

Species that are introduced to new ecosystem by activity of the human are called introduced species or non-native species. As a consequence of their introduction, existing ecosystem might get affected and this is the negative impact, like in the case above. Introduced species might become invasive species when they spread too much.
