Reactant: carbon dioxide and water

Performed by all organisms

Product: carbon dioxide and water

Reactant: sugar and oxygen

Answer 1

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 2

Carbon dioxide is added to the atmosphere by several means, one example being volcanic eruptions. Which of the following also adds carbon dioxide directly to the atmosphere. (1 point)
Responses

erosion of igneous rocks
erosion of igneous rocks

burning a forest
burning a forest

evaporation of a puddle
evaporation of a puddle

forming fossil fuels

Answer 3

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 4

Imagine you are a scientist studying carbon sinks.

Which of the following would you consider a carbon sink in your research?

(1 point)
Responses

Ocean
Ocean

Sky
Sky

Organisms
Organisms

The process of burning fossil fuels
The process of burning fossil fuels

Answer 5

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 6

What are the four main reservoirs that carbon cycles between?(1 point)
Responses

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

atmosphere, oceans, sediments, humans
atmosphere, oceans, sediments, humans

atmosphere, oceans, sediments, plants
atmosphere, oceans, sediments, plants

atmosphere, oceans, sediments, phytoplankton

Answer 7

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 8

Select whether the process listed contributes to removing carbon from the atmosphere or adding carbon back into the atmosphere.

Choose ONE selection per row

(1 point)
Photosynthesis Decomposition of dead organisms Dr. Fitz perform cellular respiration A tree performs cellular respiration to make ATP CO2 diffuses directly from air into oceans Burning fossil fuels
Another natural cause of carbon dioxide gas entering the atmosphere

Carbon is released into the soil and acts as nutrients for plants

Natural cause of carbon dioxide gas leaving the atmosphere

Large reservou storage of CO2 gas leaving the atmosphere

Natural cause of carbon dioxide gas entering the atmosphere

Man made cause of tons of carbon dioxide to enter the atmosphere

Answer 9

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 10

Carbon cycles through living and nonliving parts of the environment. Select one box in each row to identify whether carbon is released into the environment or is stored as biomass

(3 points)
releases carbon stores carbon
photosynthesis

cellular respiration

combustion

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
