Answer:
Genetic drift
Explanation:
Genetic drift is a change in genetic allele frequencies of a population. Bottleneck effect, caused by disasters such as in this case, causes genetic drift in a very rapid way hence reducing variability in a population. Reduced genetic variability in a small population is especially threatening because the chances of population surviving environmental changes get slimmer. This is because natural selection acts of genetic variability to get a population to adapt to changes in the environment.
If you want to get some energy out of an ATP molecule, all you have to do is break off one of those phosphate groups. ... The ATP hydrolysis looks more like the breaking down of polysaccharides into glucose than the catabolism of glucose itself, and this is at the core of the difference between the two molecules
A possible hypothesis here is; "If rainbow trout are eating all the macroinvertebrates, then keeping rainbow trout out of new river habitats will allow native species to recover."
A hypothesis is a statement that is tentatively put forward to explain an observation. Usually, a hypothesis is an if .... then statement. This is one of the first things that we must look out for when considering each of the statements.
Since we have observed that rainbow trout eating all the macroinvertebrates in streams and starving out other fish species, it follows that keeping rainbow trout out of new river habitats will allow native species to recover."

Answer:
Nutrient limitation occurs when meaningful additions of an essential element in additions of an essential element in biologically available forms cause an increase in the rate of a biological process and/or in the size of an important ecosystem compartment
