Sustainability is defined as the ability of an ecosystem to survive over time. How does biodiversity affect the sustainability of an ecosystem? F.
Biodiversity allows processes that take place in the ecosystem to occur in a regular pattern.

G. Biodiversity allows processes that take place in the ecosystem to cease occurring.

H. Biodiversity allows processes that take place in the ecosystem to occur only once.

J. Biodiversity allows processes that take place in the ecosystem to occur in an irregular pattern.

So basically, there are four questions.  This means that u have a 1/4 or 20% chance to get it correct.  My luck seems pretty good today, and i'm a master of guessing:).  I say it's F for F.uc.k

the real answer is b. scintillation counter

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.
