Explanation / Answer

1. The species with geographical barriers can produce number of species by interaction. Aliens such as viruses are introduced by which some intaractions will be there between these species and lead to growth in population. Hence, the population of species can increase the economic sector and lead to global transportation.

2. The introduction of alien fishes into the victoria lake led to growth of the population of species. Consequently, humans are interested infishing, so the population of humans who are fishing is more. Hence, the crocodiles get the chance to attack on more.

3. Due to the population is more in lake, diseases also will be more. As the muddy water and decomposed material around the lake is birth place for mosquitoes and lead to malaria. Fringes of the lake can produce a harmful disease such as bilharzia. The other dangerous thing is that the attack of crocodiles.

6. Miconia is a plant transported from Mexixo to Hawaii. Miconia has nature of spreading in wide areas. This nature led occupation of large areas by disrupting native plants roots. The loose contact of miconia wiht the soil led to soil erosion and landslides.

7. The subterranean termites were introduced to New Orleans from eastern Asia after world war II by wooden cargo crates and pallets.
