What will happen to an ecosystem that is experiencing a prolonged drought? The organisms in the ecosystem will either migrate or begin to die off as the available resources are no longer enough to support their numbers. The number of organisms in the ecosystem will adjust to the amount of water available.
An ecosystem can support a certain number of organisms depending on the availability of food, shelter, and water. If an ecosystem has more organisms than its water supply can support then it is beyond its carrying capacity. The ecosystem will not be able to support the organisms and they will have to either relocate or die until the ecosystem is once again at or below carrying capacity.
The resources available for the amount of organisms present will decrease in this situation. Overcrowding will result, which will lead to organisms either migrating to find resources or dying due to insufficient resources.
