QUESTION 1
Dete-rmine the approximate percentage of food obtained from producers and the approximate percentage of food obtained from consumers. Using the Table feature in your text options below (look like a window), create a 2-column table describing your food list versus feeding behavior (producer, primary consumer, etc.)
QUESTION 2
Deter-mine the approximate percentage of food obtained from producers and the approximate percentage of food obtained from consumers.
QUESTION 3
How much support do you receive from the first trophic level?
QUESTION 4
How much from the second trophic level?
QUESTION 5
In which trophic level do you belong? (consider more than this day)
QUESTION 6
If you ate more producers, how would this change the percentage of the biomass pyramid necessary to support your survival? Why?
QUESTION 7
If you ate more food from secondary consumers, how would this change the percentage of the biomass pyramid necessary to support your survival? Why?

What Trophic Level Are You?
Objective
1. Students will discover where their food comes from in nature.
2. Students will demonstrate how nature is connected and dependent on each other.
3. Students will predict how humans impact food webs.

Introduction
All of the energy that you use to perform daily tasks like exercising, thinking, and staying warm comes from the food that you eat. All of the energy in your food comes from the sun. First, plants convert light energy from the sun into chemical energy through photosynthesis. When animals eat the plants they use the process of cellular respiration to transform this chemical energy into a form their bodies can use. Animals can also get energy from eating other animals, although much of the original energy from the sun has already been used up by the animal which is eaten. In this activity you will determine where you get your food and it turn your energy.
Procedure
1. Create a list of food consumed during one day (breakfast, lunch, dinner, snacks, & beverages).
2. Label each item as from a producer (plant), a primary consumer (e.g., cow), or secondary or higher consumer (e.g., fish) based on their feeding behavior.
* If the food item contains both producers and consumers, note both and guess approximately how much of each it contains.
3. Determine the approximate percentage of food obtained from producers and the approximate percentage of food obtained from consumers.

Conclusions
How much support do you receive from the first trophic level?
How much from the second trophic level?
In which trophic level do you belong? Consider more than this day.
If you ate more producers, how would this change the percentage of the biomass pyramid necessary to support your survival? Why?
If you ate more food from secondary consumers, how would this change the percentage of the biomass pyramid necessary to support your survival? Why?
