Two species of birds feed on mistletoe berries. The birds are active at different times of the day and do not come into contact with one another. Nonetheless, the presence of one species limits the survival and reproduction of the other. What type of competition is this?
A. interference
B. exploitation
C. allelopathy
D. intraspecific

The correct answer is B. exploitation

Explanation:

Exploitation competition occurs when the interaction of two species is indirect when they complete for the same resource like food, place, etc. The use of resources by one individual species reduces the amount of resources for the other species leading to competition.

So over time the more fit species will out complete the less fit species. So here two species of bird feed on the same food but at different times and so they reduce resources for each other which is an example of exploitation competition.

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.
