Answer:
b) the effects of local evolution or migration on an exosystem
Explanation:
a) false; symbiosis is the relationship between two species with either a mutual benefit to both creatures, one benefiting and the other remaining neutral, or one being negatively affected while the other benefits. There is no relationship between the two groups of blackcaps to a is false.
b) true; the effects of local evolution or migration on an ecosystem. Local evolution has not occured yet but migration has. The effect that scientists believe may happen to the ecosystem because of the migration is the creation of a new species, which would definitely effect an ecosystem
c) false; biotic factors are the living parts of an environment, such as plants, animals, and insects. The difference in the two groups of blackcaps isn't what biotic factors they use but when their mating season is. Biotic factors have no effect whatsover.
d) false; there are no given alterations in the ecosystem. Migration patterns do not just change because of something as small as a shift in bug population. Migration habits are largely genetic, such as is the case of monarch butterflys migrating from north to south and back across the continent. If a group of blackcaps are migrating somewhere different, it has been ocurring for a while, so it isn't fault of the ecosystem that suddenly made blackcaps switch migration course.
The consequences of losing the mandate of heaven include that if the leader becomes unvirtous and people in the monarchs realm are suffering or starving from certain events seenot as a sign of ruler not being virtous, then being replaced and losing position of the emporer or being in charge is a threat. The mandate of heaven giveso you the authority to rule under the supposed word of God. Without this holy order, the people wouldn't want to follow the Supreme leader because they'd believe that they're not obligatedo tof anymore. Religion was very important at the time that the mandate of heaven was a key document in ruling political states, so it was very effective.
I'm thinking Lack of Motivation. I'm going to double check though for you.
