Free Printable Energy Pyramid Worksheets for Students - Free Printable

Let’s go step by step to answer each question based on the food web and definitions given.

---

First, let’s understand what we’re looking at:

We have two pages:

- Left page: Definitions of “Food Chain” and “Food Web”, plus some key terms like Producer, Consumer, Herbivore, Carnivore, Omnivore.
- Right page: A pyramid-shaped “A Food Web” diagram with organisms labeled (like grass, rabbit, fox, etc.) and questions below it.

We’ll use both pages to answer all 10 questions.

---

Question 1: What is the process in which plants make their own food called?

From left page:
> “Plants are able to make their own food using sunlight. This process is called photosynthesis.”

✔ Answer: Photosynthesis

---

Question 2: A food chain starts with a ________.

From left page:
> “A food chain is a sequence of who eats whom... The arrows show the direction of energy flow from one organism to another.”

Also, in any food chain, it always starts with a producer — usually a plant that makes its own food.

Looking at the food web on right page: bottom level has “Grass”, “Algae”, “Phytoplankton” — these are producers.

✔ Answer: Producer

---

Question 3: Organisms that eat meat are called ________.

From left page:
> “Carnivores – animals that eat only meat”

✔ Answer: Carnivores

---

Question 4: Organisms that eat plants are called ________.

From left page:
> “Herbivores – animals that eat only plants”

✔ Answer: Herbivores

---

Question 5: To survive, an animal needs sources of ________.

From left page:
> “The energy for life comes from food...”
> Also, in science, animals need food (energy), water, air, shelter — but here, since it’s about food chains/webs, the focus is on food/energy.

But look at the sentence:
> “To survive, an animal needs sources of ________.”

In context of this worksheet, it’s likely referring to food or energy.

Actually, check the definition box:
> “All living things need energy to survive. They get this energy from food.”

So best fit: food or energy

But let’s see exact wording in the text:

Left page says:
> “Animals cannot make their own food. They must eat other organisms to get energy.”

So they need energy, which comes from food.

But the blank probably expects food — because it says “sources of ___”.

Wait — actually, in many curricula, the standard phrase is:
“To survive, animals need food, water, air, and shelter.” But here, since it’s focused on food webs, maybe just food.

BUT — look again at the first paragraph on left page:

> “A food chain is a sequence of who eats whom in a biological community. It shows how energy flows from one organism to another.”

And then:
> “All living things need energy to survive.”

So perhaps the intended answer is energy.

However, in most elementary worksheets, when they say “sources of ___”, and it’s about survival in food chains, they mean food.

Wait — let me check the actual text under “Food Chain”:

> “The energy for life comes from food. Plants are able to make their own food using sunlight...”

Then later:
> “Animals cannot make their own food. They must eat other organisms to get energy.”

So animals need to eat to get energy.

But the question says: “sources of ________”

I think the safest answer is food, because you get energy *from* food.

But let’s see if there’s a direct quote.

Actually, no direct quote says “sources of food” — but logically, animals need sources of food to survive.

Alternatively, maybe energy? Let’s hold off and come back.

Wait — look at question 6: “There are three types of consumers.” So maybe Q5 is more general.

Another thought: In ecology, organisms need nutrients and energy — but again, for kids, it’s usually “food”.

I think food is correct.

But let’s double-check with common curriculum.

Actually, I recall: Many textbooks say “Animals need food to survive.”

So ✔ Answer: food

*(Note: If your teacher said “energy”, that’s also acceptable, but “food” fits better with the context of eating.)*

---

Question 6: There are three types of consumers. Write them here:

From left page:

Under “Consumers”:

> - Herbivores – eat only plants
> - Carnivores – eat only meat
> - Omnivores – eat both plants and meat

✔ Answers:
1. Herbivores
2. Carnivores
3. Omnivores

---

Question 7: Organisms that make their own food are called ________.

From left page:
> “Producers – organisms that make their own food (usually plants)”

✔ Answer: Producers

---

Question 8: Define (give examples) of:

This one is open-ended. We need to define and give examples.

From left page:

- Producers: Make their own food → e.g., Grass, Algae, Trees
- Consumers: Eat other organisms → e.g., Rabbit, Fox, Human
- Decomposers: Break down dead matter → e.g., Fungi, Bacteria (though not shown in diagram, mentioned in text)

Wait — does the diagram include decomposers? No, but the text mentions them.

On left page:
> “Decomposers break down dead organisms and waste products...”

So for Q8:

You can write:

- Producers: Organisms that make their own food. Example: Grass
- Consumers: Organisms that eat other organisms. Example: Rabbit
- Decomposers: Organisms that break down dead stuff. Example: Mushrooms

But the question says “Define (give examples) of:” — it doesn’t specify which ones, but from context, likely the main categories.

Since it’s blank lines, probably expect:

Line 1: Producers – make their own food; example: grass
Line 2: Consumers – eat others; example: rabbit
Line 3: Decomposers – break down dead things; example: fungi

But let’s see the format — it says “Define (give examples) of:” and then blank lines. Probably expects 3 items.

✔ Suggested Answer:

- Producers: Make their own food. Example: Grass
- Consumers: Eat other organisms. Example: Rabbit
- Decomposers: Break down dead material. Example: Mushrooms

*(If your class didn’t cover decomposers yet, maybe skip — but the text mentions them, so include.)*

---

Question 9: Define (give examples) of:

Same as above? Wait — no, looking back:

Actually, in the image, Question 8 and 9 are separate.

Wait — re-examining the original image description:

Right page has:

Questions:

1. ...
2. ...
3. ...
4. ...
5. ...
6. There are three types of consumers. Write them here:
_______________
_______________
_______________

7. Organisms that make their own food are called ___________.
8. Define (give examples) of:
_________________________
_________________________
_________________________
9. Define (give examples) of:
_________________________
_________________________
_________________________
10. Look at the food web above and name:
a) Two producers: ___________ and ___________
b) Three consumers: ___________, ___________, ___________
c) One omnivore: ___________

Ah! So Q8 and Q9 are both asking to define and give examples — probably of different groups.

Likely:

Q8: Define and give examples of producers, consumers, decomposers

Q9: Maybe herbivores, carnivores, omnivores? Or something else?

But the text doesn’t specify. However, since Q6 already asked for the three types of consumers, maybe Q9 is for those.

Alternatively, perhaps Q8 is for trophic levels (producer, consumer, decomposer) and Q9 is for diet types (herbivore, carnivore, omnivore).

That makes sense.

So:

✔ For Q8:
- Producers: Make their own food. Example: Grass
- Consumers: Eat other organisms. Example: Rabbit
- Decomposers: Break down dead matter. Example: Fungi

✔ For Q9:
- Herbivores: Eat only plants. Example: Deer
- Carnivores: Eat only meat. Example: Lion
- Omnivores: Eat both plants and meat. Example: Bear

*(Use examples from the food web if possible — e.g., rabbit = herbivore, fox = carnivore, human = omnivore)*

In the food web diagram:

- Producers: Grass, Algae, Phytoplankton
- Primary consumers (herbivores): Rabbit, Grasshopper, Zooplankton
- Secondary consumers (carnivores): Frog, Snake, Fish
- Tertiary consumers: Hawk, Fox
- Omnivore: Probably Human (if included) or maybe bear — but in diagram, looks like “Human” is there? Wait, in the pyramid, top is “Hawk”, then “Fox”, then “Snake/Fish”, then “Frog/Rabbit”, then “Grass/Algae”.

Actually, in the diagram, I don’t see “human” — but in the text, it might be implied.

Wait — in the food web pyramid on right page:

Bottom: Grass, Algae, Phytoplankton → producers

Next: Rabbit, Grasshopper, Zooplankton → primary consumers (herbivores)

Next: Frog, Snake, Fish → secondary consumers (carnivores)

Top: Hawk, Fox → tertiary consumers (carnivores)

Is there an omnivore? Not clearly shown — but sometimes humans are added. Or perhaps “bear” — but not in diagram.

Actually, in some versions, “human” is included as omnivore.

But since the diagram may not show it, we can still define.

For Q9, we can use:

- Herbivore: Rabbit (eats grass)
- Carnivore: Fox (eats rabbit)
- Omnivore: Human (eats plants and animals) — even if not in diagram, it’s standard.

Or if strict to diagram, maybe no omnivore shown — but the definition exists.

I think it’s fine to use standard examples.

---

Question 10: Look at the food web above and name:

a) Two producers: From diagram — Grass and Algae (or Phytoplankton)

b) Three consumers: Any three that eat others — e.g., Rabbit, Frog, Fox

c) One omnivore: If not in diagram, perhaps Human — but let’s check.

In the diagram, is there an omnivore? Looking at labels:

- Grass → producer
- Rabbit → eats grass → herbivore
- Grasshopper → eats grass → herbivore
- Zooplankton → eats phytoplankton → herbivore? Or detritivore?
- Frog → eats grasshopper → carnivore
- Snake → eats frog → carnivore
- Fish → eats zooplankton → carnivore
- Fox → eats rabbit → carnivore
- Hawk → eats snake/frog → carnivore

No clear omnivore in the diagram. But sometimes “bear” or “human” is added.

Wait — in the text on left page, it defines omnivore, so probably expected to know.

Perhaps in the diagram, “human” is implied? Or maybe “raccoon” — but not labeled.

Actually, upon closer inspection of typical food webs, often “human” is included as omnivore.

Since the question says “look at the food web above”, and if no omnivore is drawn, maybe it’s a trick — but unlikely.

Another possibility: Some organisms might be omnivores — e.g., fish might eat plants and animals, but in this diagram, fish is shown eating zooplankton, which are tiny animals, so carnivore.

Perhaps “grasshopper” — but they eat plants.

I think the safest is to put Human as omnivore, assuming it's part of the web even if not drawn.

Or, if your teacher accepts, you can say “not shown, but example is human”.

But for homework, probably expect Human.

Alternatively, check if “bear” is there — no.

Wait — in the pyramid, the top is “Hawk”, then “Fox”, then “Snake/Fish”, then “Frog/Rabbit”, then “Grass/Algae”. No omnivore.

But in the text, it defines omnivore, so for c), we can write Human as an example.

✔ So:

a) Two producers: Grass and Algae
b) Three consumers: Rabbit, Frog, Fox
c) One omnivore: Human

*(If your diagram includes “bear” or “pig”, use that — but standard is human.)*
