the carbon cycle and its importance

what is Carbon cycle. Carbon cycle: involves the series of processes which contribute to the circulation of carbon in nature.
i. Carbon dioxide is removed from the air mainly by photosynthesis during which plants use it to manufacture their own food.
ii. Carbon is lost in form of carbonates of calcium and magnesium through leaching and drainage in carbon cycle

THE IMPORTANCE OF ATMOSPHERIC CARBON

The atmosphere gains carbon dioxide through
i. Burning of fuel like coal and wood releases carbon for carbon cycle

ii. The action of volcanoes which releases carbon dioxide
iii. The respiration by plants and animals also involves the carbon cycle
iv. The death, decay and putrefaction of plants and animals,
v. Diffusion of carbon dioxide form sea and other bodies of water, acting as reservoir of carbon dioxide

uses of carbon cycle

the are various used of the carbon cycle which can be seen in the following ways. carbon cycle has to do with the atmospheric carbon dioxide

i. Plants use carbon dioxide obtained from the air to manufacture their food during photosynthesis
ii. It provides carbon which is the major building block of all organic matters
iii. It helps to purify the atmosphere and also to maintain atmospheric level of carbon dioxide
iv. Organic matter which is made form carbon helps replenish the soil nutrients

The carbon cycle is vital to life on Earth. Nature tends to keep carbon levels balanced, meaning that the amount of carbon naturally released from reservoirs is equal to the amount that is naturally absorbed by reservoirs. Maintaining this carbon balance allows the planet to remain hospitable for life. Scientists believe that humans have upset this balance by burning fossil fuels, which has added more carbon to the atmosphere than usual and led to climate change and global warming.

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 and function in the ways that permit the chemistry of life to occur.

Carbon in the atmosphere is mostly in the form of carbon dioxide with some methane and hydrofluorocarbons. The amount of carbon dioxide in the atmosphere is increasing. Most of the carbon entering the ocean ends up in the deep ocean where it can be carried by currents for hundreds of years or be lost in sediments.

Chlorophyll, the substance that makes algae and plants green, uses the energy from sunlight. In algae and plants it is contained in a structure called the chloroplast; cyanobacteria carry out photosynthesis directly in the cytoplasm of the cell which involves the use carbon.

The microbe uses this energy to change carbon dioxide gas from the air and the water around them into a sugar called glucose. You can check my post on glucose here. The sugar is either transported to other cells and used as food or stored as insoluble starch. This process is called photosynthesis

1. 3. 2. 1. Proper combination of factors of production: The law of diminishing returns helps the entrepreneur to combine properly the factors of production to prevent wastageChanges in scale of production: The law of diminishing returns helps entrepreneurs to change the scale of production through the variation of the quantities of all inputIt ensures efficiency: As more and more variable factors are added to a fixed factor, it eventually comes to a profitable level and productivity and efficiency are maintained using labour requires little or no formal education.public enterprisesprivate enterprises

            total output continues to increase from 10 to 30, to 60, to 120 and so on. But as the fifth (5^th) labour was used or employed, there was a drop in production from 120 to 100. This is the stage at which the law of diminishing returns sets in as every additional unit of labour brings about a decrease in the total output

   They do not use mental effort,
   rather, they make use of physical effort or energy in production, hence their jobs are popularly referred to as brown collar jobs.
