Show Answer Key & Explanations Step-by-step solution for: Ecosystems and Biomes Grade 7 Lesson
Yes, both images show ecosystems. Here’s why:

---

🌳 First Image (Forest Scene)



This picture shows a forest environment with:
- Living things (biotic factors): Trees, a bear, a deer, birds, insects, and underground organisms like worms or fungi.
- Non-living things (abiotic factors): Soil, rocks, water, air, and sunlight.

An ecosystem is defined as a community of living organisms (plants, animals, microbes) interacting with each other and their physical environment (soil, water, climate, etc.) as a system.

➡️ In this image, we can see how the animals depend on the trees for shelter and food, how roots hold the soil, and how sunlight and rain support plant growth — all parts working together. So yes, this is an ecosystem.

🦆 Second Image (Pond Scene)



This picture shows a pond habitat with:
- Living things: Ducks, fish, tadpoles, frogs, dragonflies, snails, insects, algae, and aquatic plants.
- Non-living things: Water, mud, rocks, sunlight, and oxygen in the water.

Again, this fits the definition of an ecosystem. The plants produce oxygen and food; fish eat smaller organisms; decomposers break down dead matter; and everything depends on water, sunlight, and nutrients in the soil.

➡️ You can even see how energy flows: sunlight → plants → herbivores → carnivores. That’s a classic food web — a key part of any ecosystem.

---

Final Answer:



> Yes, both images show ecosystems because they each contain living organisms interacting with each other and with their non-living environment (like soil, water, and sunlight) to form a functioning ecological unit.

💡 *Tip for students:* When deciding if something is an ecosystem, ask yourself:
- Are there plants and animals?
- Are there rocks, water, air, or sun?
- Do they depend on each other to survive?

If you can answer “yes” to all three — it’s an ecosystem!
