If over a period of 10 years a population has a logistic growth rate you would expect to see?
a stable equilibrium phase
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 type of population growth curve shows a carrying capacity?
Logistic Growth
How does the availability of resources affect whether a population's growth is exponential or logistic?
If resources are limitless than a population's growth will be exponential. Growth will be logistic in cases where there are limited resources. As the population grows closer to the logistical limit, the overall growth will slow.
What are the difference between logistic and exponential growth?
That answer was offensive and stupid
When individual in a population reproduce at a constant rate it produces a growth pattern?
It is called logistic growth.
A logistic growth pattern from an exponential growth pattern?
The growth rate in an exponential growth will continue to increase over time. In logistic growth, the growth rate will increase until it begins to level off at at the carrying capacity of an environment, where the amount of resources determines the amount of organisms that can be sustained in a given environment.
The life history pattern in which population growth is logistic is called-?
The life history pattern in which population growth is logistic is called the logistic growth model. It is characterized by an initial period of exponential growth followed by a gradual decline in growth rate as the population approaches its carrying capacity due to limited resources.
When individuals in a population reproduce at a constant rate it produces a growth pattern called?
It is called logistic growth.
Which is not a difference between a population showing exponential growth and a population showing logistic growth?
Mutation Rate
Compare the exponential model and the logistic model of population growth. (?
An exponential model has a j-shaped growth rate that increases dramatically over a period of time with unlimited resources. A logistic model of population growth has a s-shaped curve with limited resources leading to a slow growth rate.
What is logistic growth?
Population growth in which the growth rate decreases with increasing number of individuals until it becomes zero when the population reaches a maximum.
What would An s shaped population growth curve best describes what?
logistic growth
Compare exponential growth with logistic growth?
Exponential growth occurs when numbers increase by a certain factor in each successive time period. Logistic growth is population growth that starts with a minimum number of individuals and reaches a maximum depending on the carrying capacity of the habitat. In exponential growth population grows slowly when it's small, but as the population gets larger, growth speeds up. In logistic growth, when the population is small, the growth rate is fast because there are plenty of natural resources. (Logistic) As the population approaches the carrying capacity, resources become scarce. Completion for food, shelter and mates increases between individuals of a population. As a result, the growth rate slows. Exponential growth, grows fast in the beginning and then slows down. Logistic growth grows slow in the beginning and then speeds up.
What is the characteristic shape of logistic growth curve?
The classic "S" shaped curve that is characteristic of logistic growth.
What is the characteristics shape of a logistic growth curve?
The classic "S" shaped curve that is characteristic of logistic growth.
In logistic population growth what is the initial growth called?
The initial growth of a population is called a growth spurt. In logistic population growth, the population grows at a steady pace.
