Write the definition for Apparent magnitude and absolute magnitude.

Apparent magnitude and absolute magnitude

Explanation: Apparent magnitude is a phrase used by astronomers to describe how bright an object appears in the sky from earth. The magnitude scale today is based on Hipparchus' system. The brighter an object appears, the lower its magnitude.

Absolute magnitude is the magnitude a star would have if it was placed at a distance of 10 parsecs from Earth.

Apparent magnitude: astronomers use this word to describe how bright an object appears in the sky from earth.

Absolute magnitude: the magnitude (brightness) of a celestial object as it would be seen at a standard distance of 10 parsecs.

Explanation: Hope this helps!

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.
