The andes developed from a convergence between a tectonic plate carrying oceanic crust and another carrying continental crust.

TRUE

Explanation:

The Andes mountain has resulted due to the sharing of a convergent plate boundary between the Nazca plate (oceanic plate) and the South American plate (continental plate). It forms extensively the longest continental mountain ranges.

The Nazca plate, due to its greater denser subducts below the South American, as a result of which a subduction zone is created. The downgoing plate melts at greater depth and mixes up with the magma and due to the force exerted by the convection current, the magma again rises upward. This is how the San Andes mountains have formed over millions of years.  

Thus, the above statement is true.

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.
