when the population has a major change in environment or the reproduction is slow.

∙ 11y agoThere are a few reasons a population crash could occur. Two primary examples, though, are the following:
1 - The population had such a rapid reproduction rate and an initally large abundance of food (coupled with no natural predators - an introduce species) that their numbers soared in a small amount of time. Their carrying capacity reached its limit but because of the rapid reproduction, this lead to competition between animals of the same species, and their number declined rapidly.
2 - A population begins the same way as the previous example, but at their peak some form of natural disaster occurs - fire, flood, drought, saline environment - or some other form of limiting factor ensues - small breeding space, incidence of disease, territorial disputes - which causes a rapid decrease in population numbers.

a population crash
Give an example of how a symbiotic relationship could cause a population crash?
An example of how a symbiotic relationship could cause a population to crash is if a disease or parasite was to spread in a population that was dense. This could result in the population dramatically decreasing in a short period of time.
What is the characteristics response in the population size of many species to a density-independent limiting factor?
an overall decrease in population regardless of the location of the "clan"

carrying capacity
What would happen to the prey population if the predator population was removed from the graph?
There would initially be an enormous population explosion until they exceeded the available resources, then the population would suddenly crash.
4 Under what conditions might a death phase occur?
when the population decrease rapidly , it is said to crash.
