We are given a list of definitions (1–10) and a list of terms (A–J). We need to match them correctly.
| Number | Phrase | Best Match | Explanation |
|--------|--------|------------|-----------|
| 1 | Organisms that make their own food | J. Autotrophs | Autotrophs (like plants) produce their own food via photosynthesis. |
| 2 | Site of photosynthesis | A. Chloroplasts | Photosynthesis occurs in chloroplasts in plant cells. |
| 3 | Process occurs in cytoplasm | G. Glycolysis | Glycolysis is the first step of cellular respiration and takes place in the cytoplasm. |
| 4 | C₆H₁₂O₆ | D. Glucose | This is the chemical formula for glucose, a sugar used in both processes. |
| 5 | Process does not require oxygen | B. Anaerobic | Anaerobic processes occur without oxygen (e.g., fermentation). |
| 6 | Process requires oxygen | C. Aerobic | Aerobic processes require oxygen (e.g., aerobic respiration). |
| 7 | Adenosine triphosphate | E. ATP | ATP stands for adenosine triphosphate — the energy currency of the cell. |
| 8 | Energy storing molecule | E. ATP | ATP stores and transfers energy in cells. |
| 9 | The anaerobic process of splitting glucose and forming two molecules of pyruvic acid | G. Glycolysis | Glycolysis splits glucose into pyruvate without oxygen. |
| 10 | The ability to do work | H. Energy | Energy is the capacity or ability to do work. |

| | Cellular Respiration | Photosynthesis |
|---|--------------------------|--------------------|
| Reactants | Glucose (C₆H₁₂O₆) + Oxygen (O₂) | Carbon dioxide (CO₂) + Water (H₂O) + Light energy |
| Products | Carbon dioxide (CO₂) + Water (H₂O) + ATP | Glucose (C₆H₁₂O₆) + Oxygen (O₂) |
| What organelle? | Mitochondria | Chloroplasts |
> 🔍 Explanation:
> - Cellular Respiration: Uses glucose and oxygen to produce ATP, CO₂, and water. Occurs in mitochondria.
> - Photosynthesis: Uses CO₂, water, and light to produce glucose and oxygen. Occurs in chloroplasts.

Answer:
Photosynthesis and cellular respiration are complementary processes that form a cycle in ecosystems. During photosynthesis, plants use sunlight, carbon dioxide, and water to produce glucose and oxygen. The glucose made during photosynthesis is used as fuel in cellular respiration, where it reacts with oxygen to produce ATP (energy), carbon dioxide, and water. The carbon dioxide released during respiration is then used again in photosynthesis, and the oxygen produced in photosynthesis is used in respiration. This creates a continuous cycle of energy and matter between producers (plants) and consumers (animals).
> 🔄 In short:
> Photosynthesis produces the food and oxygen that organisms need for cellular respiration.
> Cellular respiration releases waste products (CO₂ and H₂O) that plants use for photosynthesis.

Answer:
Plants, algae, and some bacteria (like cyanobacteria) perform photosynthesis. These are called autotrophs because they make their own food using light energy.
> ✔ Examples: Green plants, phytoplankton, cyanobacteria.
---
Answer:
All living organisms perform cellular respiration, including plants, animals, fungi, and most bacteria. This includes both autotrophs and heterotrophs.
> 💡 Even though plants do photosynthesis, they also perform cellular respiration at night or in non-photosynthetic parts (like roots) to generate energy.

| Reactants | Glucose + Oxygen | CO₂ + H₂O + Light |
| Products | CO₂ + H₂O + ATP | Glucose + Oxygen |
| Organelle | Mitochondria | Chloroplasts |
#### 12. Relationship:
Photosynthesis and cellular respiration are interconnected cycles. Photosynthesis produces glucose and oxygen from CO₂ and water using sunlight. Cellular respiration uses glucose and oxygen to produce ATP, releasing CO₂ and water. The outputs of one process become inputs for the other, sustaining life in ecosystems.
#### 13. Photosynthesis:
Plants, algae, and some bacteria (cyanobacteria).
#### 14. Cellular Respiration:
All living organisms (plants, animals, fungi, bacteria).
