On a logistic population growth curve the growth starts to slow down after initial growth because there aren't enough resources to support as many new individuals?
exponential (<-----Apex)
When does exponential growth of a population stop?
Exponential growth may occur in environments where there are few individuals and plentiful resources but when the number of individuals become large enough resources will be depleted slowing the growth in exponential growth.
When can expendential growth happen?
when there is no competition When there are unlimited resources- Apex Exponential growth can happen anytime when the rate of the growth is increasing along with an increase in growth.
What is a condition for a population showing exponential growth?
In order to have exponential growth there must be sufficient resources to thrive. The problem with exponential growth is that since the world is finite at some point there will be overpopulation.
How is logistics growth difference from exponential growth?
linear growth is the equal growth in a equal time period without any aspects such as food to change it. Exponential growth is the growth of the population based on the culmulative things in the environment affecting the population of the area
Why cant population of bacteria or any other biological organism keep increasing exponentially forever?
Organisms start to compete for resources.
Can species undergo exponential growth forever?
It is not possible for any species to undergo exponential growth forever. There is only a finite amount of resources in terms of living space, food, air to breathe, water to drink, and so forth, and therefore a constantly growing species will eventually get to the point at which it runs out of resources. Typically this results in mass starvation and shrinkage of the overgrown species.
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.
How can exponential growth happen?
There has to be no constraints on growth due to resource scarcity (not enough food, water, space) or predators.
Is the global population growing exponentially?
Almost. Mathematical exponential growth is theoretical. There are certain restrictions to such. Social awareness, modern medicine, food supply etc., restrict true exponential growth.
Why cant the human population keep growing exponentially forever?
Population growth is limited by the supply of resources. At some point there will no longer be enough resources, such as land, fresh water, top soil to grow food in, fuel to transport the food, building materials etc to support the growing population.
WHY does the population of animal living in jungle not increases as quickly as the human population does?
Food chain, habitat resources and limited food availability restricts the growth of animals which do not implement in case of humans.
