Carbon Cycle Practice Quiz: Photosynthesis and Respiration Focus

📚 Topic Summary

The carbon cycle describes how carbon atoms continually circulate between the atmosphere, oceans, land, and living organisms. Photosynthesis and respiration are key processes in this cycle. Photosynthesis, performed by plants and algae, uses carbon dioxide from the atmosphere and converts it into glucose (sugar) for energy, releasing oxygen as a byproduct. Respiration, performed by nearly all living organisms, breaks down glucose to release energy, consuming oxygen and releasing carbon dioxide back into the atmosphere. These two processes are complementary and essential for maintaining the balance of carbon in our environment. 🌍

🧪 Part A: Vocabulary

1. Carbon Dioxide
2. Photosynthesis
3. Respiration
4. Glucose
5. Atmosphere

Definitions:

1. The process by which plants convert light energy into chemical energy.
2. A simple sugar that is an important energy source in living organisms.
3. The layer of gases surrounding the Earth.
4. A gas produced by respiration and used by plants in photosynthesis.
5. The process by which organisms break down glucose to release energy.
