Exponential Population Growth Lab Report

The following population exhibits and Exponential Growth period during Phase A of the given graph. This is visible from the graph because of the distinct J-shaped curve of the graph, this indicates that the curve is Exponential. The curve starts with stable phase not seeming to increase because the growth is slow due to the small population known as the Lag Phase. Then the growth build momentum and grows at an accelerating pace until environmental conditions prevent for their growth, this is known as the Exponential Growth Phase. To accurately calculate the population growth size from year to year the formula Nt+1=RNt is used. In this formula Nt+1 refers to population size the following year, R refers to the net reproductive rate of the species, and Nt represents the number of females already present.

During phase B of the graph there is a series
Organisms with Exponential (r) reproductive strategies (bacteria, fungi, and many insects) tend to produce a large number of offspring, tend to have a shorter lifespans, show little or no care for their offspring, and tend to be smaller organisms that mature faster. This reproductive strategy affects the population size over time by having a drastic increase in population until it reaches the carrying capacity of the environment leading to decline and the population due to the lack of resources. Organisms with Logistic (K) reproductive strategies (Bears, Whales, and humans) tend to have fever reproductive events, tend to have longer life expectancy, have more care for their offspring, and have fewer offspring. This affects population growth by having an exponential growth phase but eventually decelerating into a stable equilibrium where the number of deaths and the number of birth are about equal, this allows the population to stay under the carrying capacity of the environment to avoid a drastic decline in
