A boat traveled from a bay into a freshwater lake and brought a nonnative plant to the lake. If the new plant adapts to the fres
hwater environment, which is the most likely consequence in the lake? - Water temperature will fluctuate rapidly.
- The water will become brackish.
- Some native plant populations will increase.
- Some native plant population will decline.
If the boat brings in a nonnative plant into the lake, than that means that lake will get an invasive species. The plant that will be brought will be an invasive species as it is not native to that lake. The invasive species usually manage to out-compete the native species, often resulting in rapid increase in the numbers of the invasive species, and rapid decline, or even extinction of some of the native species as they are not able to compete with the invasive species.
Explanation: The random change in the gene pool is due to genetic drift. Remember, genetic drift occurs at a more rapid rate when the population size is reduced. The flood is a random occurrence. It could have as easily been a drought.
