The energy pyramid
By Meghan Lyle
2
Only 10% of the energy from one trophic level is transferred to the next level. Scientists have analyzed the energy (in kilograms of biomass) in each level of the food web shown here. The data is shown in the next slide.
3
Labeling
Use a calculator (or follow along) to divide and find the percent of energy that has been transferred from each level.
10.9%
Producer
Tertiary Consumer
9.5%
Decomposer
10%
Secondary Consumer
Primary Consumer
15.6%
9.6%
4
Multiple Choice
Calculate the average percent.
Does the data support the 10% rule?
Yes
No
5

What type of energy is coming into the food web?
Chemical
Heat/Thermal
Electrical
Mechanical
Radiant/Light

What are you going to donate to the village?
To raise a pig to market weight (250-300 lbs), you will need approximately 550-750 pounds of feed.
600 pounds of grain would feed 50 people for approximately 13 days.
A 250lb pig (150lbs of edible product) will feed the village 4 days.
