Answer:
The exponential growth model shows a characteristic curve which is J-shaped while the logistic grown model shows a characteristic curve which is S-shaped.
The exponential growth model is applicable to any population which doesn’t have a limit for growth. The logistic growth model is applicable to any population which comes to a carrying capacity.
The exponential growth model typically results in an explosion of the population. The logistic growth model results in a relatively constant rate of population growth. This happens when the growth rate of the population arrives at its carrying capacity.
Exponential growth is ideal for populations that have unlimited resources and space – such as bacterial cultures. Logistic growth is more realistic and can be applied to different populations which exist in the planet.
The exponential growth model doesn’t have any upper limit. The logistic growth model has and upper limit, which is the carrying capacity.
Exponential growth happens when the rate of growth is in proportion to the existing amounts. This is also true for logistic growth but the difference is, it also includes competition and resources which are limited.
This is evidenced by Doppler
shift effect. This is the phenomenon where waves that are coming from an object
that is accelerating towards your direction are heard at a higher frequency than that of
objects moving away from you. This is the same for light (which also has
wave-like properties). When observing distant galaxies, astronomers discovered that
they all showed to be redshift (change in the frequency of light towards red
color). This means that all galaxies are moving away from each other because
the universe is expanding.
