Less work power, less money, a danger for country, culture and language to dissapear.
The predator population may also decrease due to a decrease in available food source, leading to increased competition among predators. This could result in some predators migrating to find new prey or population decline due to lack of resources. Ultimately, the predator population may be negatively impacted by a decrease in the prey population.
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.
the population in the world in the mid 1600's was almost nine hundred million and then it decrease by a lot and now we have a lot more people in the world.
Population can decrease by a huge disease for example loads of people died from small pox. But such a disease is very uncommon as we have many vaccination's. Also if nuclear war starts huge amounts of people will die.
it has decreased go to http://www.census.gov/ipc/www/idb/country.php
yes we need them to keep our land hethy
The population of zoo plankton would decrease.
A decrease in the birth rate will cause a decrease in population over time.
there are many reasons a population or organisms would increase or decrease. some reasons are diseases, predator increase/decrease, good/bad weather, and enough/not enough resource's. :) yep
Death and migration are factors that can decrease hare population.
Population crash
There are many contributing factors that could be the cause for a decrease in fox population. Over population, not enough food, disease, or over hunting or poaching any of these could be the reason for a decrease in the population.
The decrease in population is 900. The Percent change is 900 / 4500 X 100 = 20% Decrease Or = -20%.
A decrease in overall population/population density.
The population of Bad Bad is 350.
It is true to say that; If a prey population decreases, the population of its predator probably will decrease as well.
The population change is a 16.8% decrease.
