Arithmetic growth refers to the division of one daughter cell obtained during mitosis while the other daughter cell enlarges and differentiates. solution: The model will then behave like a geometric model, and the population will grow, provided R>1. (Biology) A certain bacteria divides every 15 minutes to produce two complete bacteria. Arithmetic growth takes place when a constant amount is being added, as when a child puts a dollar a week in a piggy-bank.

A pattern of population growth where organisms reproduce at a constant rate at fixed intervals. Since the number of bacteria doubles every hour and there are initially 1 000, therefore at the end of the first hour there will be 2 000. The basic equation for growth is Yt = Y0( 1+r) t where Y 0 is the initial amount ($1000 in this example), r is the growth rate expressed as a decimal (.04 in this example), and t is the number of years of growth (10 in this example).

Exponential growth is growth with a constant per unit growth rate. The daughter cells formed as a result of mitosis retain the ability to divide, but slow down due to limited supply of nutrients. Thus, the impact of exponential growth on a population is enormous, as relatively few individuals can seed a large population. Komodo Dragon Facts, Diet & Habitat | What is a Komodo Dragon?
