Question

a population of giraffes on a square kilometer of the african savannah contains sixteen individuals. generally, the giraffes stay in smaller groups, surrounding scattered watering holes, where there is abundant vegetation. what is the size of the giraffe population? blank what is the population density? blank what type of distribution does this giraffe population display? ○ uniform ○ random ○ clumped done

Explanation:

Sub - question 1: What is the size of the giraffe population?

Step1: Identify population size

The problem states that the population of giraffes on a square kilometer of the African savannah contains sixteen individuals. So the population size is the number of individuals, which is 16.

Step1: Recall population density formula

Population density ($D$) is calculated as the number of individuals ($N$) divided by the area ($A$) they occupy. The formula is $D=\frac{N}{A}$.

Step2: Substitute values

We know that $N = 16$ (from the population size) and the area $A=1$ square kilometer (since it's a square kilometer of the savannah). Substituting these values into the formula, we get $D=\frac{16}{1}=16$ individuals per square kilometer.

• Uniform distribution: Organisms are evenly spaced, which is not the case here as giraffes are in smaller groups around watering holes.
• Random distribution: Organisms are distributed without a pattern, but here giraffes are grouped around watering holes (a resource), so not random.
• Clumped distribution: Organisms are grouped together around resources (like watering holes with abundant vegetation here), which matches the description of giraffes staying in smaller groups around scattered watering holes.

Answer:

16
