It looks like you've uploaded an educational worksheet titled
"L1: What Are Ecosystems?" which explains the concept of ecosystems, their components, and types. Since I can't view images directly, I’ll analyze and explain the content based on your description and the typical structure of such worksheets.
Let’s break down the key parts of the worksheet and solve any implied task:
---
🔹 What Is an Ecosystem?
An
ecosystem is a community of living organisms (plants, animals, microbes) interacting with each other and their non-living environment (sunlight, water, soil, air).
> Example: A forest ecosystem includes trees, birds, insects, soil, sunlight, and rain.
---
🔹 Living vs. Non-Living Things
-
Living things: Organisms that grow, reproduce, respond to stimuli, and need energy.
- Examples: Plants, animals, fungi, bacteria.
-
Non-living things: Physical elements that don’t grow or reproduce.
- Examples: Sunlight, water, rocks, soil, air.
> Task: Identify living and non-living things in a given scene (e.g., a pond or forest).
>
✔ Solution: In a pond, frogs and fish are *living*; water, rocks, and sunlight are *non-living*.

🔹 Types of Ecosystems
Ecosystems are categorized into two main types:
1.
Terrestrial Ecosystems – Land-based
- Examples: Forests, deserts, grasslands, tundra.
2.
Aquatic Ecosystems – Water-based
-
Freshwater: Lakes, rivers, ponds.
-
Marine: Oceans, coral reefs.
> 🌍 Example: The Amazon Rainforest is a terrestrial ecosystem; the Great Barrier Reef is a marine one.

🔹 Food Chain in an Ecosystem
The diagram likely shows a food chain:
-
Sun → Grass → Rabbit → Fox
- Energy flows from the sun to producers (grass), then to consumers (rabbit), then to predators (fox).
- Decomposers (like fungi and bacteria) break down dead matter, recycling nutrients.
> Key Concept: Energy transfer is unidirectional — it starts with the sun and moves through trophic levels.

🔹 Abiotic and Biotic Factors
|
Biotic Factors |
Abiotic Factors |
|--------------------|---------------------|
| Living components: plants, animals, microorganisms | Non-living components: sunlight, water, temperature, soil, air |
> Example: In a desert, cacti (biotic) survive due to high heat and low water (abiotic).
---
🔹 Task: Fill in the Blanks / Label Diagrams
If the worksheet has blanks or diagrams to label:
-
Label the food chain: Sun → Producer → Primary Consumer → Secondary Consumer.
-
Identify biotic/abiotic factors in a drawing (e.g., tree = biotic, rock = abiotic).
-
Match ecosystem types to examples (e.g., "coral reef" → marine ecosystem).
---
✔ Final Answer Summary:
-
Ecosystems include both living (biotic) and non-living (abiotic) components.
- Energy flows from the
sun to
producers, then to
consumers.
- Ecosystems are classified as
terrestrial or
aquatic.
-
Decomposers recycle nutrients back into the soil.
> 💡
Key Takeaway: All life depends on interactions within ecosystems — every organism has a role!

If you have a specific question from the worksheet (e.g., “Name three abiotic factors” or “Explain how energy flows”), let me know, and I’ll give a targeted answer!
