The carbon cycle shows how carbon existing in different compounds can be recycled between living organisms and the environment.
Glucose is an organic compound and all organic compounds contain Carbon. Carbon enters the atmosphere as Carbondioxide (CO2) from respiration, the CO2 is then used by plants to produce their food (carbohydrate) in a process called photosynthesis.
Animals (primary consumers) feed on plants passing the carbon compounds to other consumers along the food chain. CO2 is exhaled by these animals during respiration. These plants and animals eventually die, and their dead bodies are degraded by decomposers (microbes) returning the carbon in their body into the atmosphere as CO2 or they undergo combustion when used as fossil fuels.
The cycle that is carried out when carbohydrates are passed on along the food chain to other animals and other consumers is : The Carbon cycle when an organism eat another organism, it transfer the energy from one to the other through the carbon cycle
It's a cell wall, common to some types of cells, like plant cells (one notable component of the cell wall is <span>cellulose, which is exactly where we obtain it from</span>).
Hormones -- such as melatonin and cortisol; the former signals the body to go to bed, while the latter signals for the sleeping person to wake up -- are created by physiological changes.
