It is true to say that; If a prey population decreases, the population of its predator probably will decrease as well.
True, if the number of prey decreases, the predators will have nothing left to eat and will slowly starve. In some cases the predators will become cannibalistic (eat its own species) to prevent it self from starving to death.So the answer is true, if a prey population decreases the population of its prey will decrease as well.
Probably an increase in the population in their main predator or over hunting by humans
Population density decreases as people move away from each other. For example, when the suburbs began to be created, population density decreased in cities.

it can probably decrease the population of a country

probably because they are an easy meal for hunters (animal hunters not people)
Natural disasters are usually the main causes for population decrease. Some countries that just got hit by a natural disaster, probably went into a population decrease. Some recent countries that got a population decrease are Taiwan (huge disaster), etc.
Probably Humans or a killer whale
Probably tigers and cheetahs.
the smaller population on the food chain would increase and the big predators would decrease in population. it could probably go instinct or become very rare in that area.
If the carrying capacity suddenly decreased, you could probably expect the amount of organisms within the ecosystem to decrease as well. (There is a decreased amount of room/resources for the organisms, causing the quantity of organisms to decrease as well.) hope that helps :)
