Review the chart, which shows the population sizes of three african animals in 1990 and in 2000. 1990 → 2000 lions . 100,000 .→ 47,000 cheetahs 50,000 → 7,500 zebras 15,000 → 2,500 which explanation is best supported by the numbers in the chart? a)lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetahs. b)the dwindling zebra population has led to the decline of the predator lion and cheetah populations. c)overhunting of lion and cheetah populations has led to a decline in the food source population. d)lion and cheetah populations compete for the food source of zebras, and cheetahs outcompete lions.

A.

Explanation:

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.  

thinking it would be d not too sure but i think it's right
