Both Gene and Chromosomal mutations. They can change a DNA sequence and affect generic information. Gene mutations change several nucleotides, where chromosomal mutations can change the number or structure of a whole chromosome.
Answer:
Water Withdrawal: it has happened in some lakes in Minnesota
Explanation:
The water cycle is influenced by seasonal-climatic fluctuations and human activity. Water withdrawal is one of the human activities that most seriously affect the amount of water in lakes and aquifers by reducing water storage, thereby altering the flow in streams, lakes and wetlands. Concerning this situation, the state of Minnesota incorporated 1- the use of a US database (State Water Use Database, SWUD) with useful water use information on withdrawals and consumptive uses and 2- an index based on the sum of permitted water withdrawal from surface and groundwater. This index estimates the use of water as a percent of the surface water runoff to define and predict the vulnerability of lakes, using data from 54 stream gages recorded from 1988-2007. The catchment scores are scaled from 0 to 100 depending on the percent of runoff used.

It has been shown that biodiversity of an area has a large impact on the ecosystem stability of that area. ... This increase in complexity makes it more likely that the ecosystem will return to a stable state after a disturbance, because the ecosystem has more ways to respond to a disturbance and fix problems.
