Question

1. The effect of initial population sizes on the growth of populations of an organism was

Answer 1

When graphing data, we must consider the variables, label axes, define units of measure. In this case, variables are initial population size / final population size, showing an directly proportional relationship.

-------------------------------------

We need to construct a graph illustrating the data in the table.

We can make a dispersion graph. To do it, we need to define variables.

Since we want to know how different initial population sizes affect population growth,

• the independent variable is the initial population size
• the dependent variable is the final population size (after 24 hours)

The final population size depends on the initial population size. This is, the number of individuals at the beginning will influence the final number of individuals.

• Initial population sizes ⇒X horizontal ax ⇒Unit: Number of individuals
• Final population sizes ⇒ Y vertical ax ⇒ Unit: Number of individuals

By making a dispersion graph, we can represent the effect of the varying initial population sizes on the final population sizes. We can compare these effects and observe how populations grow as the N₀ increases.

We can also choose a bar graph. In this way, we can compare initial and final population sizes.

This graph will show populations and two bars per population.

• Blue bar ⇒N₀⇒ Initial population size
• Red bar ⇒N₁ ⇒ Final population size

• Different populations ⇒ 1, 2, 3, 4, 5 ⇒ Represented in the X horizontal ax

• The number of individuals ⇒ from 1 to 324 ⇒ Represented in the Y vertical ax.

By making a bar graph, we can represent initial and final population sizes and compare them. The population that begins with 1 individual, after 24 hours has 4 individuals. The population that begins with 3 individuals, ends with 9 individuals. And so on.

No matter which graph you choose, you will observe a directly proportional relationship between both variables. The bigger is the initial population size, the bigger it ends after 24 hs.
