Hope this helps :)

Option B

Explanation:

The plants uptake the nitrogen by the help of the nitrogen fixing bacteria found in the soil.

The nitrogen from the plants is taken by the animals eating the plants. The source of the nitrogen to the animals is the plants containing nitrogen.

The plants are also supplied with some of the fertilizers that contains adequate amount of nitrogen in it, which is transferred to the animals when they eat it.

the cell cycle is the final answer! : )

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.
