Primary functions of the medusa?

The primary function of medusa is to carry out sexual reproduction and to allow the species to disperse to different locations.

Explanation:

There are two distinct cnidarian body forms: polypoid and medusoid.

The medusa is more of an umbrella or bell shape, with the mouth facing down. The body of the medusa is often called the bell. Medusae are usually free-swimming and either propel themselves using muscle contractions or float along water currents like plankton.

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.
