question 59

Essay

Refer to the table.
Table 4
Determine the structure of the energy pyramid for your study area. Use the numbers of individuals of each species in Table 4 (for this question, do not include the omnivorous species). Assume that all individuals of all species have the same biomass.
a) Collect the data you would need to construct the energy pyramid from Table 4 and use it to create a new table (this will be referred to as Table 5). The columns should be category, number of individuals, number of half the individuals (negative), and number of half the individuals (positive). Under the category column should be the following rows: primary producers, herbivores, primary carnivores, and secondary carnivores. Fill in the rest of the table.
b) Use these data to graph the energy pyramid for your study area (this will be referred to as Figure 3). To aid in creating the graph, once you have determined the total number of individuals in each category, divide the number of individuals by half. One half will be plotted on the left of the graph (as negative) and one half will be plotted on the right of the graph (as positive). Your graph should be centered around a y-axis at 0. Label each step in the energy pyramid with the category name (e.g., herbivores) from the table.
c) Based on Figure 3, what type of ecosystem are you studying?

Definitions:

Intercostal Muscles

Muscles located between the ribs that aid in the process of breathing by controlling the expansion and contraction of the chest cavity.

Elevate Ribs

The action of lifting the ribs through muscle contraction, which increases the volume of the thoracic cavity to aid in inhalation.

Emphysema

A long-term, progressive disease of the lungs characterized by a loss of elasticity and enlargement of air spaces, leading to breathing difficulties.

Trachea

A large tube in the respiratory system that connects the larynx to the bronchi, allowing air passage to the lungs.
