North Atlantic Drift moderates much of the air temperature over northwestern Europe.
Is not Mediterranean Drift or Black Sea because Mediterranean Sea and Black Sea are located in south-est of Europe.
Invasive species are successful in novel environment due to lack of natural predator or competition. Therefore if the non-native share a niche with other fish in the lake ecosystem, there will definitely be competition for resources. This could lead to competitive exclusion of one species or resource partitioning between the species consequently, the non-native fish species will not invade the new environment unchecked. I hope this helps
The correct answer is 4.) Eventually they become separate species
A process of formation of a new species from an existing species is called speciation.
When a single species changed into two or more separate species, is called speciation. Speciation can take place due to reproductive isolation. In reproductive isolation, the separated species no longer can interbreed among themselves. This is happened due to mating differences, sterility or environmental barriers which finally results into the adaptive splitting into two species.
