“which of the following represents the appropriate method for calculating the number of tusk less females in the year the population was at its lowest due to poaching”

The year of 1995 has the lowest population of females elephants (100 females). The population of 100 female elephants contains both the tusk and the tuskless females. The percentage of tuskless female elephants in the same year was 40%. Therefore, the number of female elephants without tusk can be calculated by using the following formula or method:

Let x be the total number of elephants.

∴ The number of tuskless females = = 40

Hence, the answer is the option C.

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.  

the answer is c.
