Ecosystem Worksheet with vocabulary matching activity and definitions for biotic and abiotic factors.

Let's solve the Ecosystem Worksheet step by step.

---

🔍 Objective:

Match each vocabulary word on the left to the correct picture on the right based on the definitions provided.

---

📚 Definitions Recap:

- Abiotic factor: non-living things
- Biotic factors: living things
- Carnivore: animal that eats only meat
- Consumer: living thing that must eat for energy
- Decomposer: living thing that breaks down dead organisms for energy
- Herbivore: animal that only eats plants
- Omnivore: animal that eats meat and plants
- Producer: living thing that produces its own energy via photosynthesis

---

✔ Step-by-step Matching:

We’ll go through each vocab term and match it to the correct image.

---

#### 1. Abiotic factor → Sun
- The sun is a non-living thing (light, heat) that affects ecosystems.
- ✔️ Match: Sun

---

#### 2. Biotic factors → Group of animals and plants (bottom image with people, frogs, plants, etc.)
- This image shows living things (plants, animals, humans).
- ✔️ Match: Scene with multiple living organisms

---

#### 3. Carnivore → Bird of prey (eagle/hawk)
- A carnivore eats only meat. The eagle is a predator.
- ✔️ Match: Eagle

---

#### 4. Consumer → Shark
- Consumers are living things that need to eat for energy. Sharks eat other animals.
- ✔️ Match: Shark

> Note: *Many animals are consumers*, but shark is a clear example.

---

#### 5. Decomposer → Earthworm or fungus-like creature?
- Wait — the image next to "Decomposer" looks like an earthworm, which is a decomposer.
- Earthworms break down dead organic matter.
- ✔️ Match: Earthworm

---

#### 6. Herbivore → Raccoon? Or another animal?
- Looking at the images:
- Raccoon is shown — but raccoons are omnivores (eat plants and meat).
- Wait — the image of the raccoon might be misleading.

Wait — let’s check all images carefully:

List of images from top to bottom:
1. Raccoon → likely omnivore
2. Earthworm → decomposer
3. Sun → abiotic
4. Shark → carnivore/consumer
5. Tree → producer
6. Eagle → carnivore
7. Scene with people, frogs, plants, etc. → biotic factors
8. Insect (grasshopper?) → herbivore?

Ah! Let's re-express the images in order:

From top to bottom (right column):

1. Raccoon – omnivore
2. Earthworm – decomposer
3. Sun – abiotic
4. Shark – carnivore
5. Tree – producer
6. Eagle – carnivore
7. Scene with diverse living things – biotic factors
8. Grasshopper – herbivore

Now let's match correctly.

🔁 Final Matching:

| Vocab Word | Correct Image | Reason |
|------------------|---------------|--------|
| Abiotic factor | Sun | Non-living (sunlight, energy source) |
| Biotic factors | Scene with people, frogs, plants, etc. | Shows many living things |
| Carnivore | Eagle | Eats meat (predator) |
| Consumer | Shark | Must eat for energy (not producer) |
| Decomposer | Earthworm | Breaks down dead material |
| Herbivore | Grasshopper | Eats plants (plant eater) |
| Omnivore | Raccoon | Eats both plants and meat |
| Producer | Tree | Makes its own food via photosynthesis |

---

✔ Final Answer: Draw lines as follows:

- Abiotic factor → Sun
- Biotic factors → Scene with living things (people, frogs, plants)
- Carnivore → Eagle
- Consumer → Shark
- Decomposer → Earthworm
- Herbivore → Grasshopper
- Omnivore → Raccoon
- Producer → Tree

---

🧠 Explanation Summary:

- Producers (like trees) make their own food using sunlight.
- Consumers (like sharks, eagles) must eat others.
- Herbivores eat only plants (grasshopper).
- Carnivores eat only meat (eagle).
- Omnivores eat both (raccoon).
- Decomposers recycle dead matter (earthworm).
- Abiotic = non-living (sun).
- Biotic = living things (the scene with many organisms).
