a.
If the population is larger than the environment can support, more will die until the population size is back to or lower than the environment can support.

Just as a p.s., the death rate may be catastrophically high if the environment is destroyed by the over-population - especially human population which is devastating the natural world.

A is your best option here.

If a population begins to exceed the ability of a given environment to support it, then food and other resources become scarce, making it likely that some animals/plants won't be able to survive. Also, in their weakened condition, more such animals/plants fall pray to predators and disease, because they can't fend them off. So, the death rate probably will rise.

B is unlikely under these conditions because there will be fewer animals/plants who survive to adulthood to reproduce, and those who do will likely be unable to produce viable offspring.

Option C is such an absurd choice that it doesn't even really merit discussion. If the death rate fell, it would simply serve to accelerate the depletion of environmental resources and lead to an even more cataclysmic decline in population numbers at some future date. It would simply be a temporary delay of the inevitable.

D doesn't necessarily have to occur, but one can argue that this is almost an inescapable consequence of a burgeoning population in an area with rapidly dwindling food and other natural resources needed to produce and sustain new life. For one thing, among sexually reproducing organisms, there will be fewer females to produce offspring, and fewer males to fertilize those females to produce the offspring. Hence, a drop in the birthrate is likely. However, other factors may come into play, like superfertile males or females who, through natural selection pressures, are able to produce large numbers of offspring. But the latter scenario is a remote possibility.

A. because if the carrying capacity of the environment surpassed, than the environment cannot support that many organisms, therefor the death rate must fall until it is back bellow the carrying capacity

large wars are mandatory to administration inhabitants or it is going to strengthen so large that the worldwide heavily isn't waiting to administration and we can initiate die ing besides from the dimensions of the means mandatory for foodstuff water and growth it is going to do us extra harm then good being over populated large conflict worldwide conflict is coming as i write this and for one straightforward reason administration inhabitants straightforward !!!! Greg Bickerton --- do you ask your self why each and all of the worldwide wealth is controlled via basically a million% of the inhabitants and the different 7% are wealthy and the ninety 4% relax stay decrease than the poverty line and national Dept is an identical the dep. is so large its extra proper to diminish the inhabitants via a million/3 than to maintain letting it advance a million/6 each twelve months and administration it

D.

if we could get all of these extremists who feel "god gave me 5 babies to have a once (even though she was artificially helped to conceive at all) and i a'gonna have 'em all god be praised"... um if it is god's will that you are helped to concieve how is it not also his will that you abort the children that will be born deformed with horrible defects, physical or mental.

The increment will compensate for the increase. Mother nature has many variables ,so if the CO2 increasees the plant growth will increas. The plants need the CO2 as bad as u need oxygen.
