In your own words explain how the process of radioactive decay is used to accurately date fossils

Radioactive elements or isotopes are atoms which release radiations over time and this cause decrease in their amount and convert to other isotope. This is also known as radioactive decay.

Half life: Half life of an radioactive element is the time, after which the amount of element remains half.

To accurately date fossils, we should know the half life of an element.

In radioactive decay one isotope change to other by emitting radiations with time. We check the amount of secondary isotope and then relate it to half life of element to know the time that how much time take to make this secondary element.

six grader is what i am ssorry

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.
