Answer 6

Here is the correct matching of the information given with the respective processes:

**Photosynthesis**
- Product: sugar and oxygen
- Reactant: carbon dioxide and water

**Cellular Respiration**
- Performed by all organisms
- Product: carbon dioxide and water
- Reactant: sugar and oxygen

Answer 7

The correct response that adds carbon dioxide directly to the atmosphere is:

**burning a forest**

Burning forests releases stored carbon dioxide from trees and vegetation into the atmosphere.

Answer 8

The correct response that you would consider a carbon sink in your research is:

**Ocean**

Oceans act as significant carbon sinks by absorbing large amounts of carbon dioxide from the atmosphere.

Answer 9

The correct response regarding the four main reservoirs that carbon cycles between is:

**atmosphere, oceans, sediments, terrestrial biosphere**

This option captures the main reservoirs where carbon is stored and cycled.

Answer 10

Here is how each process contributes to carbon cycling with respect to removing carbon from or adding carbon back into the atmosphere:

1. **Photosynthesis** - Removing carbon from the atmosphere
2. **Decomposition of dead organisms** - Adding carbon back into the atmosphere
3. **Dr. Fitz performs cellular respiration** - Adding carbon back into the atmosphere
4. **A tree performs cellular respiration to make ATP** - Adding carbon back into the atmosphere
5. **CO2 diffuses directly from air into oceans** - Removing carbon from the atmosphere
6. **Burning fossil fuels** - Man-made cause of tons of carbon dioxide to enter the atmosphere
7. **Another natural cause of carbon dioxide gas entering the atmosphere** - Adding carbon back into the atmosphere
8. **Carbon is released into the soil and acts as nutrients for plants** - Natural cause of carbon dioxide gas leaving the atmosphere
9. **Natural cause of carbon dioxide gas leaving the atmosphere** - Removing carbon from the atmosphere
10. **Large reservoir storage of CO2 gas leaving the atmosphere** - Removing carbon from the atmosphere

Answer 11

Here’s how carbon behaves in each of the processes listed:

1. **Photosynthesis** - **stores carbon**
(Plants take in carbon dioxide and convert it into organic matter.)

2. **Cellular respiration** - **releases carbon**
(Organisms break down glucose and release carbon dioxide as a byproduct.)

3. **Combustion** - **releases carbon**
(The burning of organic materials or fossil fuels releases carbon dioxide into the atmosphere.)

So the selections would be:

- **Photosynthesis**: stores carbon
- **Cellular respiration**: releases carbon
- **Combustion**: releases carbon
