Here is the step-by-step solution to fill in the blanks on the Energy Pyramid worksheet.
Left Side: The Pyramid Levels
1. Producers (Bottom Level)
*
Make food: Producers make their own food through a process called
photosynthesis.
*
Using the sun's energy through: This happens via
photosynthesis.
*
Equation at the bottom: This is the chemical equation for photosynthesis.
* $6\text{CO}_2 + 6\text{H}_2\text{O} + \text{sunlight \& chlorophyll} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2$
* Blanks:
$\text{CO}_2$,
$\text{H}_2\text{O}$,
$\text{C}_6\text{H}_{12}\text{O}_6$ (or Glucose),
$\text{O}_2$
2. Primary Consumers ($1^{\text{st}}$ Consumer)
*
Eats: They eat
producers / plants.
*
Can be an: Since they eat plants, they can be an
herbivore OR
omnivore.
3. Secondary Consumers ($2^{\text{nd}}$ Consumer)
*
A: A secondary consumer is a
carnivore or
omnivore.
*
Eats the: It eats the
primary consumer.
4. Tertiary Consumers ($3^{\text{rd}}$ Consumer)
*
Eats: They eat
secondary consumers.
*
Called the: In a simple chain, they are often called the "
top predator" or "
apex predator" of the food chain.
5. Top Text (Organisms use...)
* Organisms use the
energy released in the food chain to
power all of their daily activities through the process of
cellular respiration.
*
Equation at the top: This is the reverse of photosynthesis (Cellular Respiration).
* $\text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \rightarrow 6\text{H}_2\text{O} + 6\text{CO}_2 + \text{Energy (ATP)}$
* Blanks:
$\text{C}_6\text{H}_{12}\text{O}_6$ (Glucose),
$\text{O}_2$,
Energy (or ATP)

Right Side: Definitions & Roles
6. Food Chain
* Series of events in which one organism eats another and obtains
energy.
* Each level is called a "
trophic" level.
7. Food Web
*
Many overlapping food
chains in an ecosystem.
8. Decomposers
*
Break down material and release
nutrients into soil.
9. Scavenger
* Carnivore that
feeds on
dead organisms.
10. The Sun
* The cycle
begins with light energy from the sun.

Final Answer
Left Column (Top to Bottom):
*
Top Paragraph: energy, power, cellular respiration
*
Top Equation: $\text{C}_6\text{H}_{12}\text{O}_6$ (Glucose), $\text{O}_2$, Energy (ATP)
*
Tertiary Consumers: secondary, top predator (or apex predator)
*
Secondary Consumers: carnivore, omnivore, primary
*
Primary Consumers: producers, herbivore, omnivore
*
Producers: photosynthesis, photosynthesis
*
Bottom Equation: $\text{CO}_2$, $\text{H}_2\text{O}$, $\text{C}_6\text{H}_{12}\text{O}_6$ (Glucose), $\text{O}_2$
Right Column (Top to Bottom):
*
Food Chain: energy, trophic
*
Food Web: Many, chains
*
Decomposers: Break, nutrients
*
Scavenger: feeds, dead
*
The Sun: begins
