Levels of Organization - ESL worksheet by missalessandra - Free Printable

Let's solve this "Levels of Organization" Worksheet no. 2 step by step.

This worksheet asks you to identify the correct level of biological organization for each image, based on what is typically taught in science classes (especially for 8th grade). The levels of organization in biology go from smallest to largest:

1. Cell
2. Tissue
3. Organ
4. Organ System
5. Organism
6. Population
7. Community
8. Ecosystem
9. Biosphere

Now, let’s analyze each image and determine the correct level of organization.

---

🔹 Image 1: Cell (with organelles like nucleus, mitochondria, etc.)

- This shows a eukaryotic cell, likely an animal or plant cell.
- Level: Cell

✔ Answer: *Cell*

---

🔹 Image 2: Group of similar cells forming a sheet-like structure

- This looks like epithelial tissue — many cells arranged in layers.
- Level: Tissue

✔ Answer: *Tissue*

---

🔹 Image 3: Brain

- The brain is an organ made up of tissues (nervous tissue, connective tissue, etc.).
- Level: Organ

✔ Answer: *Organ*

---

🔹 Image 4: Mushroom (fungus)

- A mushroom is a complete organism, even though it's not an animal.
- It can grow, reproduce, and carry out life processes.
- Level: Organism

✔ Answer: *Organism*

---

🔹 Image 5: Butterfly

- A butterfly is a living, individual creature — a multicellular organism.
- Level: Organism

✔ Answer: *Organism*

---

🔹 Image 6: Group of butterflies (same species)

- This shows multiple individuals of the same species together.
- This is a population.
- Level: Population

✔ Answer: *Population*

---

🔹 Image 7: Group of different animals (giraffe, elephant, rhino, etc.)

- These are different species living together (e.g., in a savanna).
- This represents a community of organisms interacting.
- Level: Community

✔ Answer: *Community*

---

🔹 Image 8: Aquatic scene with plants, animals, water, soil, etc.

- Shows living organisms (fish, turtle, ducks, plants) and non-living components (water, sunlight, soil).
- This is a complete ecosystem.
- Level: Ecosystem

✔ Answer: *Ecosystem*

---

🔹 Image 9: Earth with hands holding it (symbolizing the whole planet)

- This represents the entire biosphere — all ecosystems on Earth where life exists.
- Level: Biosphere

✔ Answer: *Biosphere*

---

✔ Final Answers (in order):

| Image | Level of Organization |
|-------|------------------------|
| 1 | Cell |
| 2 | Tissue |
| 3 | Organ |
| 4 | Organism |
| 5 | Organism |
| 6 | Population |
| 7 | Community |
| 8 | Ecosystem |
| 9 | Biosphere |

🎨 Bonus Instruction:

> *"Color each image."*
You can color them creatively, but make sure to label each one correctly with its level of organization.

💡 Summary of Levels:

- Cell → Tissue → Organ → Organ System → Organism → Population → Community → Ecosystem → Biosphere

This sequence shows how life is organized from simple to complex.
