Population grow until this stage is reached?
Population grow until the stage of carrying capacity is reached. At this point, the population growth rate is equal to zero.
When would expect to see a species go through a logistic growth pattern?
A logistic growth pattern occurs when the population reaches its carrying capacity, at which point the population growth is zero.
What is the effect of exponential growth on population?
In exponential growth, the number of individuals in a population grows rapidly. With more individuals comes an increased demand for resources, food, competition, etc. There is never an unlimited amount of such resources, so a population growing exponentially is eventually limited by the amount the population can take from its environment. This limitation -- the point that a population exceeds its means -- is called the carrying capacity. Sometimes an exponentially-growing population will grow past its carrying capacity for a time before dipping back down and leveling off. In some cases (like with humans), the carrying capacity can be pushed further and further with adaption (or with humans-- innovation).
What is the study of evolution from a genetic point of view?
population genetics
What is ecological unstable equilibrium?
an equilibrium point at which, if either population changes, the population sizes will diverge from, rather than return to, the equilibrium point; a combination of population sizes at which the two populations could coexist, but when the combination changed, no impetus exists to return to the equilibrium population sizes.
The point at which the population size levels off is called the?
The carrying capacity.
What happens to a population when the size of the population reaches carrying capacity?
starvation increases to the point where this population is maintained.
The is the point at which environmental resources limit population growth.?
The ___________ is the point at which environmental resources limit population growth.
What happen when a population reach its carrying capacity?
Ideally a population at its carrying capacity is stable, there is enough for all to survive. The system is usually slightly underdamped and the population will vary between just over its carrying capacity where some individuals suffer and under its capacity where there is a surplus. If the system is severely under damped there are extreme swings in the population. A typical example is the relation between Arctic hares and foxes.
Population grow until this stage is reached?
Population grow until the stage of carrying capacity is reached. At this point, the population growth rate is equal to zero.
What would carrying capacity look like on a graph?
It depends on what the carrying capacity is plotted against.
Describe the conditions under which logistic growth occurs?
logistic growth is when a population experiences exponential growth but at a certain point is limited because the population exceeds its carrying capacity.
When would expect to see a species go through a logistic growth pattern?
A logistic growth pattern occurs when the population reaches its carrying capacity, at which point the population growth is zero.
What happens to a population when the number of individuals approaches carrying capacity?
starvation increases to the point where this population is maintained.

In exponential growth, the number of individuals in a population grows rapidly. With more individuals comes an increased demand for resources, food, competition, etc. There is never an unlimited amount of such resources, so a population growing exponentially is eventually limited by the amount the population can take from its environment.

In some cases (like with humans), the carrying capacity can be pushed further and further with adaption (or with humans-- innovation).
Why cant populations continue to grow larger and larger forever?
It then reaches the carrying capacity point.
What happens if the carrying capacity is exceeded?
It will likely descend into warfare as happened on Easter Island, and savagery will continue until the population drops below whatever remains of the carrying capacity. However, the warfare may also diminish both the human resources and Natural Resources and infrastructure to the point that no meaningful recovery is possible. Think TSE's "not with a bang, but a whimper".
