The rate at which population size grows or declines depends on the rate of________. a. births b. deaths c. immigration d. emigration c. immigration d. emigration

Everyone. So population size depends on multiple processes, so births will increase the population size, while deaths will decrease the population size. And so if we think about immigration, that's organisms coming into a population, so that increases that population. Or you can have immigration, which is when organisms leave a populations so again decrease. And these all effect the rate of the population size. So the answer is of all of the above.

In this problem, we need to figure out what the factors are that affect population size. Now one thing that can happen is organisms can be born or die so we can say birth minus deaths would be one factor in population growth. Now what else is there in a population? Organisms don't have to die to leave, so there can be immigration. And also organisms can enter the habitat and joined the population. And that's immigration. So we can say, plus the number of immigrants minus the number of immigrants, and this expression gives us the population rate of King.

All populations go through a period of growth and decline. What does such depend on the growth and decline of populations depends on births, deaths, immigration and immigration, mhm.

Hello, everyone. Today we're going to solve a problem. Number 25 here. DP by the the minus can't beat equals. And so p off t equals minus que onda que off t equals integrating factory coz e integral minus k duty which is equal to us to mine escaping. So because you know the power Katie Integral and it is a power minus Katie duty so b equals evil about Katie minus end by K into the pole minus Katie plus C so p will be equal toe minus and different by K plus C to the power. Katie, this is General solution. So at T equals zero be equal. Do be not so P note will be called tau minus and they were a big K plus c u to the power zero. So sequel toe be not plus and developed by k p equal to minus endeavored by K plus Be not plus and they were a big K. It is too, Katie. So period eyes equal toe dp by d p which is equal to be not care plus and in tow. The power Katie. Thank you
