Describe the logistic model of population growth give the characteristics of species that follow this model of population growth

Expert Solution
Step 1- Introduction

The simplest example of population growth is binary fission in protozoa and microbes starting with 1 individual (generation zero) there will be 2, 4, 8, 16, 32, 64, and so on in the succeeding generation, fission which is Synchronous.

Step 2- Explanation

If the biotic potential of a population is measured under optimal growth conditions, it is referred to as the intrinsic rate of natural increase. The "r" of the logistic equation.

This optimal condition not only includes the physiochemical environment in which population growth is maximum but also one with a stable age distribution in which there is an absence of negative feedback effects of increasing density.

Biology homework question answer, step 2, image 1A) Arithmetic scale for population size.

B) Logarithmic scale for population size

 

Step 3

The Logarithmic plot is a straight line that means the number added in any time period is proportional to the number present at the beginning of the period.

The intrinsic rate is calculated by its natality and mortality, most of the population does not show exponential increase because their environment prevents this from happening.

In an Ecosystem, other species present, a variety of abiotic conditions acts in a way that a given population will have an upper sized limit that cannot be exceeded, this limit is known as CARRYING CAPACITY OF THE ENVIRONMENT FOR THAT POPULATION.
