Explanations:
The incorrect statement in the given text is "In logistic growth, population passes well beyond the carrying capacity of the ecosystem." This statement is not true as the logistic growth curve shows that the population growth rate slows down as it approaches the carrying capacity of the ecosystem, which is the maximum number of individuals that a particular habitat can support.
Exponential Growth:
Exponential growth occurs in organisms such as bacteria, lemmings, and other small organisms when resources are unlimited. The population grows at an accelerating rate, resulting in a J-shaped curve, which has two phases: lag and log. The lag phase is the initial period of slow growth, while the log phase is the period of rapid, exponential growth.
Logistic Growth:
Logistic growth is more realistic than exponential growth as it takes into account the carrying capacity of the ecosystem. In logistic growth, the population grows slowly initially, accelerates as it approaches the carrying capacity, and finally slows down as it reaches the maximum limit of the ecosystem's resources. The logistic growth curve has an S-shaped pattern.
Carrying Capacity:
The carrying capacity is the maximum number of individuals that a particular habitat can support. It depends on the availability of resources such as food, water, and shelter. When the population size exceeds the carrying capacity, the resources become limited, which leads to competition for resources, resulting in a decline in the population size.
Conclusion:
In conclusion, the incorrect statement in the given text is that the population passes well beyond the carrying capacity of the ecosystem in logistic growth. Logistic growth takes into account the carrying capacity, and the population growth rate slows down as it approaches the carrying capacity. Exponential growth occurs in organisms such as lemmings, and logistic growth is more realistic as it considers the carrying capacity of the ecosystem.
