The Carbon Cycle Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what’s on both sides.
  • Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

What is the carbon cycle?

The carbon cycle describes how nature reuses carbon atoms, involving many living organisms.

Name the five main stores of carbon.

Air (CO2), Soil, Fossil fuels, Animals and Plants.

How do plants remove carbon dioxide from the atmosphere?

During photosynthesis, plants absorb CO2 and convert it into glucose, which can be turned into carbohydrates, proteins and fats.

What happens to carbon in plants after they absorb it?

Plants release some carbon back into the atmosphere through respiration and pass it to animals and microorganisms when eaten.

Describe the process of decomposition in the carbon cycle.

Decomposers break down dead organisms, releasing carbon as CO2.

In low oxygen conditions, dead organisms can turn into fossil fuels over millions of years.

What is the equation for respiration?

Glucose + Oxygen → Water + Carbon dioxide
