How does the rapid reproduction in bacteria cause them to evolve quickly?

Bacteria reproduce through binary fission. Each time this happens, there is a certain chance that a mutation will occur. This is measured through mutation rates. Generally, these rates are low. However, bacteria not only live short lives, but they also reproduce extremely fast. Thus, due to the high reproduction rates, mutations can accumulate rapidly in a population.

It is similar to the process of making a copy of a copy. However, there is some dirt on the xerox's plate. Thus, the copy will have these spots. Now, if you make a copy of a copy, this second copy will have double the amount of spots (mistakes) than the original. Now image this proces going on and on and on.

Not all the copies will survive, as not all mutations are beneficial (the process of natural selection). However, even if a small percentage survive (have advantageous mutations) and the copying process (binary fission) occurs fast enough, mutations will accumulate quickly. This will lead to a quick evolutionary process.

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
