Carbon Cycle
What are the processes of the carbon cycle
• Photosynthesis • Respiration • Decay process and decomposers • Combustion
What are the stages of the carbon cycle
1. Photosynthesis 2. Respiration in plants 3. Feeding 4. Death and waste 5. Respiration in plants 6. Decomposition 7. Fertilisation 8. Combustio
Explain the stages of the carbon cycle
1. Plants absorb carbon dioxide in the atmosphere to make carbohydrates through a process called photosynthesis 2. Other organisms transfer carbon into their tissues as they feed on they feed on plants and other organisms. 3. All cells contain carbon compounds such as carbohydrates, proteins and fats. This is how carbon is passed from the atmosphere as carbon dioxide, to living things. 4. Carbon returns to the atmosphere as carbon dioxide again through the process of respiration when living organisms break down food using oxygen they breath in from the air to obtain energy for their life processes, carbon dioxide is a product of this reaction
What are the main groups of a decomposer
Bacteria and fungi are the main groups of decomposer
What is combustion
Combustion is the process whereby a substance dioxide and water vapour. A large amount of heat is also given off. is burnt in oxygen to produce carbon
What is combustion
Combustion is the process whereby a substance is burnt
What is decay
Decay is an essential life process that digests food or waste matter and recycles materials.
What does the process of photosynthesis do in the carbon cycle
Green plants and algae remove carbon dioxide from the atmosphere by photosynthesis. The carbon becomes part of complex such as carbohydrates (example glucose)
How does carbon get into the atmosphere
Living things produce carbon dioxide when they respire, die and decompose or combust. (Forest fires, or when humans burn fossil fuels) Volcanic emissions contain carbon dioxide
What does in the decay process and decomposers the do in the carbon cycle
Materials from living things decay after the organisms. They are digested (broken down) by microorganisms. These microorganisms cause decay by releasing enzymes that break down compounds to be absorbed by their cells.
How does carbon leave the atmosphere
Oceans absorb carbon dioxide from the atmosphere. Plants photosynthesise, absorbing carbon dioxide from the atmosphere.
What does the process of respiration the do in the carbon cycle
Organisms return carbon dioxide to the atmosphere by respiration. It is not just animals that respire. Plants, algae and microorganisms do too.
What is the carbon cycle
The carbon cycle shows how carbon moves between stores in the form of carbon dioxide in the atmosphere to plants and animals in the form of carbohydrates, proteins and lipids in their tissues, to the soil and beneath as organic matter and fossils and then back into the atmosphere again.
What are the activities combistion is part of the natural carbon cycle
When we bum agricultural waste, wood and even biogas given off from decaying food, the carbon in these compounds combines with oxygen gas in air to form carbon dioxide. This is part of the natural carbon cycle.
What are the ways combustion isn't part of the natural carbon cycle
When we burn fossil fuels in cars, and in of carbon dioxide are introduced into the atmosphere. This does not form part of the natural factories to power thermal plants, large amounts carbon cycle because it introduces an excess amount of carbon dioxide than the plants can recycle to maintain the natural balance. This leads to high levels of carbon dioxide in the atmosphere.
What are the main groups of decomposers
bacteria and fungi
