Question

John and Tom decide to go camping for the weekend next to a lake. They spend the morning hiking to the lake and enjoy their afternoon attempting to fish some lake trout, without much luck. Luckily, they brought a cooler bag with some food to prepare burgers and baked potatoes for dinner. Before sunset, they light up a campfire using some logs they found on the ground and prepare their delicious dinner.

Answer 1

Here’s how each statement aligns with photosynthesis, cellular respiration, or neither:

1. **During the day, the trees absorb rays from the sun.**
- **Response:** Photosynthesis

2. **Tom uses the glucose from the potato to digest the burger.**
- **Response:** Cell respiration

3. **The algae in the lake release CO2 into the atmosphere at night.**
- **Response:** Cell respiration (Note: Algae perform photosynthesis during the day but can respire at night, releasing CO2.)

4. **The log burns in the campfire.**
- **Response:** Neither (The burning of logs is a combustion reaction, not directly related to photosynthesis or cellular respiration.)

5. **The grass takes in CO2 during the day.**
- **Response:** Photosynthesis

6. **John breathes in O2 from the air.**
- **Response:** Cell respiration (Since he uses the O2 for cellular respiration.)
