Question 1
1.

Question 2
2.

Earth can be divided into four systems. The atmosphere is the air above Earth’s surface. The hydrosphere is composed of all of Earth’s water. The geosphere is the rocky, non-living part of Earth. The biosphere consists of all living things, including people. Some scientists use the term “anthroposphere” to describe everything made or modified by humans.

Question: How does carbon move between the atmosphere, hydrosphere, biosphere, and geosphere?
Question 3
3.

Question 4
4.
Read the description for Land animals. How did the carbon atom get from land plants into the animal?

Land animals __________ plants (or other animals that eat plants) for energy.
Question 5
5.

Question 6
6.
Identify where each sphere is represented in this example of the carbon cycle.
Other Answer Choices:
hydrosphere
geosphere
atmosphere
biosphere
Question 7
7.

What is one reason that the carbon cycle is important to living things and the environment?

You may type your answer or use the blue "+" the record your response.

Part 2

Background information: Fossil fuels, such as coal, oil, and natural gas, formed over millions of years from the remains of ancient plants and animals. The burning of fossil fuels, as well as other human activities, increases the amount of carbon dioxide in the atmosphere.

Question: How does human activity affect the carbon cycle?

Question 11
11.

In general, how do many human activities influence the carbon cycle?

You may type your answer or use the blue "+" the record your response.

In the process of photosynthesis, plants take in carbon dioxide (CO2) from the atmosphere and water (H2O) from the soil.

Using the energy of sunlight, plants build molecules of glucose (C6H12O6) and oxygen (O2).

How do plants on Earth affect the amount of carbon in Earth’s atmosphere?
Increase the amount
Decrease the amount
Have no effect on the amount
Animals eat plants and produce carbon dioxide and water.

How do animals affect the amount of carbon in Earth’s atmosphere?
Increase the amount
Decrease the amount
Have no affect on the amount
From the Earth's Atmosphere, a carbon atom can go to land plants, oceanic CO2 and exposed rock.

Read the description of land plants. How did the carbon atom get from the atmosphere to a plant?

Photosynthesis
Cellular respiration
Transpiration
The carbon atom returns to the Atmospheric CO2. How did the carbon atom get from land animals back to the atmosphere?

Cellular respiration
Photosynthesis
Transpiration
