What is the carbon cycle short answer?
What is the carbon cycle short answer?
The carbon cycle is the process in which carbon travels from the atmosphere into organisms and the Earth and then back into the atmosphere. Plants take carbon dioxide from the air and use it to make food. Animals then eat the food and carbon is stored in their bodies or released as CO2 through respiration.
What is the correct order of the carbon cycle?
Consumer → Photosynthesis → Decomposers.
Which are the two main processes in carbon cycle?
In the natural carbon cycle, there are two main processes which occur: photosynthesis and metabolism. During photosynthesis, plants use carbon dioxide and produce oxygen. During metabolism oxygen is used and carbon dioxide is a product.
What is an example of a carbon cycle?
For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. Animals that eat plants digest the sugar molecules to get energy for their bodies. Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle.
What happens first in the carbon cycle?
Stage one: Carbon enters the atmosphere by – respiration in organisms (e.g. animals breathing) – combustion (e.g. burning of fossil fuels/ wood) – decomposition and decay (microorganisms respiration) Stage two: Carbon Dioxide is absorbed by producers in photosynthesis.
Why is carbon important to living things?
The Importance of carbon in living things Is based on the fact that it is the chemical element on which the existence of life is based. Its ability to form polymers makes it an ideal partner for molecules that generate life. Carbon is a key chemical element for life and the natural processes that take place on earth.
What is the carbonate cycle?
The carbonate–silicate geochemical cycle, also known as the inorganic carbon cycle, describes the long-term transformation of silicate rocks to carbonate rocks by weathering and sedimentation, and the transformation of carbonate rocks back into silicate rocks by metamorphism and volcanism.
What is the amount of carbon on Earth?
Earth contains about 121,000,000 GtC, which is 121 million gigatons of carbon or 121 million billion metric tons of carbon. Some atmospheric carbon dioxide gets dissolved into oceans and lakes. When that CO 2 is taken up by aquatic plants, its place is taken by more CO 2 from the atmosphere.
What is carbon Cy?
car′bon cy`cle n. 1. the biological cycle by which atmospheric carbon dioxide is converted to carbohydrates by plants and other photosynthesizers, consumed and metabolized by organisms, and returned to the atmosphere through respiration, decomposition, and the combustion of fossil fuels.
