What did charles darwin discover as a result of his experiments with breeding pigeons? desirable traits can be selected for and bred in offspring. humans can create new species through selective breeding. dogs and plants can be bred the in same way as pigeons. the pigeons had distinctive traits that were passed on to offspring

The most appropriate answer would be "Desirable traits can be selected for and bred in offspring".

Charles Darwin gave the theory of evolution and explained the process of natural selection.

Natural selection is a gradual process by which nature favors the survival of organisms present with particular traits.

By natural selection, organisms with those particular or desirable traits tend to reproduce and survive more.

These desirable traits are passed onto the offspring and gradually spread throughout the population.

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.
