1. The brown tree snake is native in areas such as Australia and eastern Indonesia. In those ecosystems, the brown tree snake is not causing the decline of bird or tree
populations. So what makes this same species damaging in Guam? Identify some
characteristics a species may possess that would fuel its ability to cause ecological
damage, as the brown tree snake has in Guam. Provide some reasoning for why
you chose these characteristics.

1 digestive system

2 stomach

3 bladder

4 carbon deoxide

5 tiger

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.
