- Why Is The Carbon Cycle Important?
The carbon cycle is the cycle by which carbon moves through our Earth’s various systems. The carbon cycle is influenced by living things, atmospheric changes, ocean chemistry, and geologic activity are all part of this cycle. The levels of carbon are at an all-time high, largely due to human activities.
Carbon is an essential element for life as we know it because of its ability to form multiple, stable bonds with other molecules. This is why nucleotides, amino acids, sugars, and lipids all depend on carbon backbones: carbon provides a stable structure that allows the chemistry of life to happen.Without carbon, none of these molecules could exist ...
Carbon in the Atmosphere
To become part of the carbon cycle, carbon atoms start out in a gaseous form. Carbon dioxide gas – CO2– can be produced by inorganic processes, or by the metabolisms of living things. Before Earth had life on it, carbon dioxide gas likely came from volcanic activity and asteroid impacts. Today, carbon is also released into the atmosphere through the activities of living things, such as the exhalations of animals, the actions of decomposer organisms, and the burning of wood and fossil fuels by...
Producers Absorb Carbon
“Producers” – organisms that produce food from sunlight, such as plants – absorb carbon dioxide from the atmosphere and use it to build sugars, lipids, proteins, and other essential building blocks of life. For plants, CO2 is absorbed through pores in their leaves called “stomata.” Carbon dioxide enters the plant through the stomata and is incorporated into containing carbon compounds with the help of energy from sunlight.Plants and other producer organisms such as cyanobacteria are crucial t...
Producers are Eaten
“Consumers” are organisms that eat other living things. Animals are the most visible type of consumer in our ecosystems, though many types of microbes also fall into this category. Consumers incorporate carbon compounds from plants and other food sources when they eat them. They use some of these carbon compounds from food to build their own bodies – but much of the food they eat is broken down to release energy, in a process that is almost the reverse of what producers do. While producers us...
The carbon cycle consists of many parallel systems which can either absorb or release carbon. Together, these systems work to keep Earth’s carbon cycle – and subsequently its climate and biosphere – relatively stable.Below are some examples of parts of Earth’s ecosystems that can absorb carbon, turn carbon into living matter, or release carbon back...
The carbon cycle, under normal circumstances, works to ensure the stability of variables such as the Earth’s atmosphere, the acidity of the ocean, and the availability of carbon for use by living things. Each of its components is of crucial importance to the health of all living things – especially humans, who rely on many food crops and animals to...
Jul 30, 2017 · Photosynthesis Definition. Photosynthesis is the biochemical pathway which converts the energy of light into the bonds of glucose molecules. The process of photosynthesis occurs in two steps. In the first step, energy from light is stored in the bonds of adenosine triphosphate (ATP), and nicotinamide adenine dinucleotide phosphate (NADPH).
Apr 27, 2017 · Chemosynthesis is the conversion of inorganic carbon-containing compounds into organic matter such as sugars and amino acids. Chemosynthesis uses energy from inorganic chemicals to perform this task.

Aug 17, 2019 · Chemosynthesis is the conversion of carbon compounds and other molecules into organic compounds. In this biochemical reaction, methane or an inorganic compound, such as hydrogen sulfide or hydrogen gas, is oxidized to act as the energy source.
