Answer: Non- native species can help to maintain the population of another species why hunting on them, can help in cross-pollination, can add to the biodiversity of the place and can also add to the yield of nutritional plants. E.g. bees are non-native in many parts around the world, but they form the backbone of cross-pollination and hence help to have a high yield of crops and plants. Most of the crops that we depend on nutrition for, are non-native. Non-native species of pets can protect us from a number of pests. Thus non-native species can form a harmonious balance in another ecosystem and even though often looked at as problematic, can prove to be rather useful.
