# What is the difference between logistic growth and exponential growth graphs?

## What is the difference between logistic growth and exponential growth graphs?

In logistic growth, a population’s per capita growth rate gets smaller and smaller as population size approaches a maximum imposed by limited resources in the environment, known as the carrying capacity ( K). Exponential growth produces a J-shaped curve, while logistic growth produces an S-shaped curve.

## How are exponential growth and logistic growth related?

Exponential population growth: When resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve. When resources are limited, populations exhibit logistic growth. In logistic growth, population expansion decreases as resources become scarce.

What is the difference between exponential growth and logistic growth quizlet?

Exponential growth = individuals are not limited by food or disease; the population will continue to grow exponentially; not realistic. The graph is described as a “J curve.” Logistic growth = the population begins to grow exponentially before reaching a carrying capacity and leveling off.

How do you explain exponential growth?

Exponential growth is a process that increases quantity over time. It occurs when the instantaneous rate of change (that is, the derivative) of a quantity with respect to time is proportional to the quantity itself.

### What is the key difference between exponential and logistic growth models of population dynamics?

The exponential growth model describes a population with unlimited resources, which keeps growing bigger and faster over time. The logistic growth model describes a population that has limited resources or other limits to growth, which grows more slowly as it gets larger.

What is a logistic growth pattern?

As competition increases and resources become increasingly scarce, populations reach the carrying capacity (K) of their environment, causing their growth rate to slow nearly to zero. This produces an S-shaped curve of population growth known as the logistic curve (right).

What is exponential growth and what does it look like on a graph?

An exponential growth function can be written in the form y = abx where a > 0 and b > 1. The graph will curve upward, as shown in the example of f(x) = 2x below. Notice that as x approaches negative infinity, the numbers become increasingly small.

## How are exponential and logistic growth models similar how are they different quizlet?

Logistic growth occurs when there are limited resources due to competition; it slows, stops, and has a period of exponential growth. Exponential growth occurs when there is unlimited resources due to little competition; individuals produce at a constant rate.

## What’s the difference between dN DT and R?

In these models, dN/dt changes over time (depends on t), but r stays the same (does not depend on t). Also, r is a per capita growth rate, meaning that it’s measured per individual, whereas dN/dt is measured for the overall population.
