Question

1. what percentage of plants, vertebrates and arthropods are found in your biome? write your answers in the appropriate space on your biome bag data sheet. you must show your work for all calculations.

total type of species in biome / total number of species in biome x 100 = percent (%) of species

1. draw, label, and color the pie graph below to illustrate the percentage of organisms in your biome. cut and paste your pie chart into your biome booklet.

Explanation:

Step1: Identify the formula

The formula to find the percentage of a type of species in the biome is $\frac{\text{Total Type of Species in Biome}}{\text{Total Number of Species in Biome}}\times100$. However, since no actual data about the number of species is provided in the question, we can't perform the actual calculation. But the general steps for calculating percentages for plants, vertebrates and arthropods would be as follows:
Let $n_1$ be the number of plants, $n_2$ be the number of vertebrates, $n_3$ be the number of arthropods and $N$ be the total number of species in the biome.
For plants:

Step2: Calculate plant - percentage

The percentage of plants $P_1=\frac{n_1}{N}\times 100$.
For vertebrates:

Step3: Calculate vertebrate - percentage

The percentage of vertebrates $P_2=\frac{n_2}{N}\times 100$.
For arthropods:

Step4: Calculate arthropod - percentage

The percentage of arthropods $P_3=\frac{n_3}{N}\times 100$.

For drawing the pie - graph:

1. Calculate the central angles for each category. The central angle for a category is given by $\theta=\text{Percentage}\times3.6$. For example, for plants, the central angle $\theta_1 = P_1\times3.6$.
2. Draw a circle.
3. Use a protractor to mark the angles for each category (plants, vertebrates, arthropods) and label each sector with the corresponding category name and percentage.
4. Color each sector with a different color.

Since no data is given, we can't provide numerical answers for the percentages. But the above are the steps to follow for both calculation and drawing the pie - graph.

Answer:

No numerical answers can be provided as no data about the number of species is given. Follow the steps above for calculation and drawing the pie - graph when data is available.
