Let's solve the
Photosynthesis and Cellular Respiration Quiz step by step, based on the diagram provided.

🔹 Understanding the Diagram:
The image shows the
interconnection between photosynthesis (in plants) and
cellular respiration (in animals). It highlights how energy flows through ecosystems and how molecules are exchanged.

✔ Step-by-Step Explanation & Answers:
####
1. Photosynthesis in Plants:
Plants use
sunlight,
carbon dioxide (CO₂), and
water (H₂O) to produce
glucose (C₆H₁₂O₆) and
oxygen (O₂).
The equation is:
> 6CO₂ + 6H₂O + sunlight → C₆H₁₂O₆ + 6O₂
This process occurs in the
chloroplasts of plant cells.

####
2. Cellular Respiration in Animals:
Animals consume glucose (from eating plants or other animals) and oxygen to produce
energy (ATP),
carbon dioxide, and
water.
The equation is:
> C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy (ATP)
This process occurs in the
mitochondria of animal cells.

Now let’s fill in the blanks:
---
🔤 Filling in the Blanks:
1.
(energy poor)
→ This refers to the input for
photosynthesis:
carbon dioxide (CO₂) and
water (H₂O)
But since it says "energy poor" and only one blank, and the arrow points from the rabbit to the plant, it must be
carbon dioxide — which is a waste product from animals and used by plants.
✔ Answer: Carbon Dioxide (CO₂)
2.
(energy poor)
→ This is the other input for photosynthesis:
Water (H₂O)
Water enters the plant roots and is used in photosynthesis.
✔ Answer: Water (H₂O)
3.
(energy rich)
→ This is the product of photosynthesis:
Glucose (C₆H₁₂O₆)
Glucose is stored energy that can be used by organisms.
✔ Answer: Glucose
4.
→ This arrow goes from the plant to the animal. The animal eats the plant, so it gets
glucose (or food).
✔ Answer: Glucose
5.
→ This is the
waste product of cellular respiration:
Carbon Dioxide (CO₂)
Also shown as going back to the plant.
✔ Answer: Carbon Dioxide (CO₂)
6.
→ This points to the
mitochondrion in the animal cell. That's where
cellular respiration takes place.
✔ Answer: Mitochondrion
7.
→ This points to the
chloroplast in the plant cell. That's where
photosynthesis occurs.
✔ Answer: Chloroplast
---
✔ Final Answers:
1.
Carbon Dioxide (CO₂)
2.
Water (H₂O)
3.
Glucose
4.
Glucose
5.
Carbon Dioxide (CO₂)
6.
Mitochondrion
7.
Chloroplast

🔄 Summary of the Cycle:
-
Plants use CO₂ and H₂O + sunlight → make
glucose and O₂.
-
Animals eat plants → get glucose → use it with O₂ in mitochondria → produce ATP, CO₂, H₂O, and heat.
- CO₂ and H₂O are released back into the environment → used again by plants.
This creates a
continuous cycle of energy and matter between producers (plants) and consumers (animals).
