🔍 Summary of the Reading Passage

The passage explains:
- An ecosystem includes all living (biotic) and non-living (abiotic) things interacting in an area.
- Abiotic factors: non-living parts like water, sunlight, soil, minerals, air, climate.
- Biotic factors: living parts such as plants, animals, fungi, bacteria.
- Producers (e.g., plants) make their own food via photosynthesis using sunlight, carbon dioxide, and water.
- Consumers (animals) eat other organisms for energy.
- Decomposers (fungi and bacteria) break down dead matter, returning nutrients to the soil.
- All organisms depend on each other and the environment to survive.

✔ Answer Key with Explanations

#### Q.1: Which of the following is living part of the ecosystem?
a. Abiotic
b. Biotic
c. Decomposers
d. Producers

✔ Correct Answer: b. Biotic

🔹 Explanation:
- "Biotic" refers to living components of an ecosystem (like plants, animals, fungi).
- "Abiotic" refers to non-living parts (like water, sunlight, soil).
- While decomposers and producers are types of living things, they are subsets of biotic factors.
- So the best answer that defines the *category* of living parts is "Biotic."

#### Q.2: True or False: Some living things need sunlight to make food.
a. True
b. False

✔ Correct Answer: a. True

🔹 Explanation:
Plants, algae, and some bacteria use sunlight in photosynthesis to make their own food. This process converts light energy into chemical energy. So yes, some living things do need sunlight to produce food.

---

#### Q.4: All populations living in a certain area make up a _____.
a. Population
b. Community
c. Species
d. None of the above

✔ Correct Answer: b. Community

🔹 Explanation:
- A population = all individuals of one species in an area.
- A community = all populations (all species) living together in an area.
- A species = a group of similar organisms that can interbreed.
- Therefore, multiple populations form a community.

#### Q.6: Fungi and Bacteria are called _____
a. Producers
b. Consumers
c. Decomposers
d. None

✔ Correct Answer: c. Decomposers

🔹 Explanation:
Fungi and bacteria break down dead plants and animals into simpler substances, recycling nutrients back into the soil. They are essential decomposers in the ecosystem.

---

#### Q.8: Which of the following is the non-living parts of the ecosystem?
a. Biotic factors
b. Abiotic factors
c. Producers
d. Decomposers

✔ Correct Answer: b. Abiotic factors

🔹 Explanation:
- Abiotic factors = non-living components (water, sunlight, temperature, soil, etc.)
- Biotic factors = living components
- Producers and decomposers are both living (biotic), so they don’t count as non-living.

#### Q.10: Which of the following things does animal give off that plants need to make food?
a. Carbon dioxide
b. Mineral
c. Sunlight
d. None of these

✔ Correct Answer: a. Carbon dioxide

🔹 Explanation:
Animals breathe in oxygen and exhale carbon dioxide. Plants use this carbon dioxide during photosynthesis to make glucose and oxygen. So, animals provide carbon dioxide, which is essential for plant food production.

📝 Final Answers Summary:

| Question | Answer | Explanation |
|--------|--------|-----------|
| Q.1 | b. Biotic | Living parts = biotic factors |
| Q.2 | a. True | Plants need sunlight for photosynthesis |
| Q.4 | b. Community | All populations = community |
| Q.6 | c. Decomposers | Fungi & bacteria break down dead matter |
| Q.8 | b. Abiotic factors | Non-living parts = abiotic |
| Q.10 | a. Carbon dioxide | Animals release CO₂ used by plants |

💡 Teaching Tips (for educators):

- Use real-life examples: e.g., a forest ecosystem has trees (producers), deer (consumers), mushrooms (decomposers), soil, water, sunlight (abiotic).
- Emphasize interdependence: Plants give O₂ and food; animals give CO₂ and help pollination; decomposers recycle waste.
- Discuss how human activity can disrupt ecosystems (pollution, deforestation).
