What impact does el nino have on the fishing industry a. an increase in the numbers of sea birds depletes the fish supply b. nutriants no longer come to the surface, so fish die or migrate c. ocean temperature are too warm for fish d. fisherman are unable to fish with intense winds and currents

The answer is B. The reason behind this is that El Niño decreases the rate of upwelling of water on the coast. Upwelling occurs when cold, nutrient-rich water “wells up” from the surface. If this process is disrupted manly due to El Niño, the movement of marine life is also affected. As a result, fish either migrate or die due to lesser nutrients coming up in the surface.

answer: oof wait

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.
