The carbon cycle involves a series of processes by which carbon compounds are interconverted in the environment. Carbon flows between each reservoir on the earth in an exchange called the carbon cycle, which has slow and fast components. Test out what else you know about this cycle by taking up the quiz below. All the best!

• 1.

### What is one thing that releases carbon into the atmosphere?

• A.

Food

• B.

Burning Fossil Fuels

• C.

Decay

B. Burning Fossil Fuels
Explanation
Burning fossil fuels releases carbon into the atmosphere. Fossil fuels such as coal, oil, and natural gas contain carbon that has been stored underground for millions of years. When these fuels are burned for energy, the carbon is released as carbon dioxide (CO2) gas. This process is a major contributor to the increase in CO2 levels in the atmosphere, leading to climate change and global warming.

### How much Carbon is in the air (%) ?

• A.

0.0354

• B.

0.03

• C.

0.33

• D.

0.033

B. 0.03
Explanation
The correct answer is 0.03 because it is the closest value to the actual percentage of carbon in the air, which is approximately 0.03%.

### What do organisms that make their own food take from the air?

• A.

Nitrogen

• B.

Oxygen

• C.

Carbon

• D.

Helium

C. Carbon
Explanation
Organisms that make their own food, such as plants, use carbon dioxide from the air during the process of photosynthesis. Carbon dioxide is converted into glucose, a form of sugar that serves as a source of energy for the organism. Oxygen is also taken in from the air during photosynthesis, but it is not the primary substance that organisms that make their own food obtain from the air. Nitrogen and helium do not play a significant role in the process of making food, making carbon the correct answer.

### Animals, plangts, fungi, and some bacteria produce Carbon during respiration.

• A.

True

• B.

False

A. True
Explanation
Animals, plants, fungi, and some bacteria produce carbon during respiration. Respiration is a metabolic process that occurs in living organisms, where they break down organic molecules to release energy. During this process, carbon dioxide (CO2) is produced as a byproduct. Animals, plants, fungi, and certain bacteria all undergo respiration, and therefore, they all produce carbon in the form of CO2. Hence, the statement "Animals, plants, fungi, and some bacteria produce Carbon during respiration" is true.

### The Carbon Cycle was popularised by?

• A.

Al Bino

• B.

Dimitri Mendeleev

• C.

Humphry Davy

• D.

Albert Orwell

• E.

Brighton Early

• F.

Bob

• G.

Bill

C. Humphry Davy
Explanation
Humphry Davy is the correct answer because he was a British chemist who popularized the concept of the Carbon Cycle through his research and experiments. He discovered the element carbon and its various forms and studied its interactions and transformations in the environment. His work laid the foundation for our understanding of how carbon moves through different reservoirs such as the atmosphere, biosphere, and geosphere, and how it is exchanged between living organisms and the environment.
