Roles in Energy Transfer Worksheet - WordMint - Free Printable

Let's solve this matching exercise step by step. The task is to match each numbered definition on the left with the correct term from the list on the right (A–J).

---

Definitions and Matching Answers:

1. uses energy to make food
→ This describes organisms that produce their own food using sunlight, water, and carbon dioxide.
✔ Answer: F. photosynthesis
*(Note: While "producer" or "autotroph" might seem relevant, the definition specifically says "uses energy to make food," which refers to the process, not the organism. So, photosynthesis is the correct choice.)*

2. another word for producer
→ Producers are also called autotrophs because they make their own food.
✔ Answer: G. autotroph

3. gets energy and nutrients by breaking down remains of other organisms
→ This is the role of decomposers (like fungi and bacteria).
✔ Answer: C. decomposer

4. organism that eats other organisms to get energy
→ Any organism that consumes other organisms for energy is a consumer.
✔ Answer: J. consumer

5. a consumer that eats plants only
→ This is a herbivore (e.g., rabbit, cow).
✔ Answer: I. herbivore

6. a consumer that eats other animals
→ This is a carnivore (e.g., lion, hawk).
✔ Answer: E. carnivore

7. consumer that eats both plants and animals
→ This is an omnivore (e.g., humans, bears).
✔ Answer: B. omnivore

8. path of energy transfers from producers to consumers
→ This describes a food chain (e.g., grass → rabbit → fox).
✔ Answer: H. food chain

9. feeding relationships among organisms in an ecosystem, made up of many food chains
→ A food web shows multiple interconnected food chains.
✔ Answer: D. food web

10. process plants use to produce food and oxygen
→ This is photosynthesis.
✔ Answer: F. photosynthesis
*(Wait — we already used F for #1. But here’s the issue: both 1 and 10 refer to the same process. Let's check carefully.)*

Wait! Problem: Duplicate Answer?

- #1: "uses energy to make food" → This could be interpreted as the *process* (photosynthesis) or the *organism* (producer/autotroph).
- #10: "process plants use to produce food and oxygen" → Clearly refers to photosynthesis.

So, both #1 and #10 point to F. photosynthesis?

But in a matching exercise, each letter should be used only once unless stated otherwise.

Let’s reevaluate:

---

Re-evaluate #1:

> 1. uses energy to make food

This is a bit ambiguous. But if we interpret it as an organism that uses energy to make its own food, then it refers to a producer or autotroph.

But the answer choices include:
- A. producer
- G. autotroph

So perhaps #1 is meant to be matched with A. producer or G. autotroph.

But #2 says: “another word for producer” → clearly G. autotroph

So:
- #2 = G. autotroph
- Then #1 = A. producer

And #10 = F. photosynthesis

That makes sense.

Now let’s fix:

---

Final Correct Matching:

1. uses energy to make food → A. producer
*(Because it's describing what a producer does — uses energy to make food.)*

2. another word for producer → G. autotroph

3. gets energy and nutrients by breaking down remains of other organisms → C. decomposer

4. organism that eats other organisms to get energy → J. consumer

5. a consumer that eats plants only → I. herbivore

6. a consumer that eats other animals → E. carnivore

7. consumer that eats both plants and animals → B. omnivore

8. path of energy transfers from producers to consumers → H. food chain

9. feeding relationships among organisms in an ecosystem, made up of many food chains → D. food web

10. process plants use to produce food and oxygen → F. photosynthesis
