5. assume two habitats have the same number of species. one habitat is predominantly one
species with just a few of the other species. the other habitat has equal numbers of all the
different species. which will have the highest diversity index?
6. why do you think the process was repeated three times?
7. there are many human-caused losses of biodiversity, such as habitat destruction and
introduction of invasive species. are there any natural events that could alter the diversity
index?
8. how do invasive species change the diversity index?
9. what do you think would happen to a habitat if the plant diversity declines?

well it definitly does because if you are seen as weak you will be seen as unimportant and they will walk all over you and the us is the most powerful military and the largest in the world

in the united states, the president is controlled by the

constitution, and in all respects subordinate to it. insofar

as it deals with presidential power, however, the american

constitution has proved to be a highly malleable document.

with very few exceptions,' the constitutional provisions relating to the president have not been changed at all since

they were ratified in 1787. but in the late twentieth century, those provisions do not mean what they meant in

1787. the constitution is a legal document, and it is enforced judicially; but its meaning was hardly fixed when it

was ratified. in particular, the contemporary president has

far broader powers than the original constitution contemplated. it is remarkable but true that large-scale changes in

the authority of the president have been brought about

without changes in the constitutional text, but nevertheless

without significant illegality.

this is a paradox. is it not clear that constitutional

changes, if not textual, are illegal? the paradox has considerable relevance to our current thinking about the presidency in particular and about constitutionalism in general.

perhaps the framers of the american constitution feared

legislative power most of all; 2 but from well-known events

in the twentieth century, it is possible to conclude that it is

presidential power that holds out the greatest risks to both

liberty and democracy. the president is by far the most visible leader in the nation; he is often the only person in government with a national constituency. moreover, he is
